JavaScript - Java Program
Im writing this code for a gas station program. I have been writing and improving my code for about 3 weeks now and its quite long. I have about classes , customer class, office class and a gas pumps classes. I need help on how to get started on finding the total output at the end of the day. Conceptually i know what i have to do but I don't know where to begin writing the code. I think each time there is a new customer i should add the amount of fuel purchased to a new total fuel purchases variable in the gas pump class. If any one could give me some advice or tips on my theory it would be great ! Should I create a method or can i be done without one.
Code: import java.util.Random;
import java.util.Scanner;
public class Customer
{
private String carTag;
private double gasPurchased;
private int gasType;
public Customer ()
{
Random gen = new Random ( );
carTag = "";
for (int i = 1; i <= 6; i++)
{
//a random number between 48 and 90
int code = gen.nextInt (43)+ 48;
if ((code <= 64) && (code >= 58))
{
i--;
continue;
}
carTag += ((char)(code));
}
System.out.println ("a car arrives; tag number:" + carTag);
}
public int getGasType ()
{
Scanner inputDevice = new Scanner (System.in);
//1:regular, 2:plus, 3:premium
System.out.println ("enter type of gas to buy " +
"(1:regular, 2:plus, 3:premium): ");
gasType = inputDevice.nextInt ();
return gasType;
}
public double getGasPurchased ()
{
Random gen = new Random ();
gasPurchased = gen.nextDouble ()* 50;
return gasPurchased;
}
public String getCarTag ()
{
return carTag;
}

GasPump pump1 = new GasPump ( );
GasPump2 pump2 = new GasPump2 ( );
Random gen = new Random ();
//asuumint gas tanks always have gas, will upgrade later
do
{
int whatHappens = gen.nextInt (100);
if (whatHappens == 5)
{
System.out.println ("gas station closed");
break;

Hi everyone , I have been working with java script for a couple of weeks now and have run into some practice obstacles, ok so I am trying to build a html java program for my website and I wants there to be a web page in which users can dynamically change the styles of page elements (e.g.,background, text) by typing the style name into a dialog box. So basically enter a word and the that word should be set to change the attributes once entered in. Ive tried working with if else statements but have run into many problems. Again I am a beginner and am trying to self teach myself if you all could help me that would be great. Thanks Sash Hey guys, Here's the program. Quote: import java.util.Random; import java.util.Scanner; public class HighLowGame { public static void main(String[] args) { Random rand = new Random(); int numberOfTries = 0; Scanner input = new Scanner(System.in); char repeat; char ans; int guess; boolean win = false; do { System.out.println("Pick a number between 0 and 10: "); guess = input.nextInt(); numberOfTries++; int numberToGuess = rand.nextInt(10); if (guess == numberToGuess) { win = true; System.out.println("Congratulations you have won!"); } else if (guess > numberToGuess) { System.out.println("Your guess was high try again"); } else if (guess < numberToGuess) { System.out.println("Your guess was low try again"); } System.out.println("The number was " + numberToGuess); System.out.println("You guessed the number in "+ numberOfTries + " attempt(s)"); System.out.println("New game? 1 for Yes, or any other number to quit "); ans = input.next().charAt(0); } while (ans == 1); } } Two questions, why doesn't my program let me keep putting in numbers until I guess the right one? What is wrong with my loop? Pressing 1 should repeat the program, any other number should close. Thanks! JAVA not JavaScript create an application, searcher that takes two command line arguments: the starting directory and the target to find. Searcher makes use of a recursive algorithm with the method signatu public static void scan (String path). This recursive algorithm needs to scan through directories and over file names in order to locate the specified file from the command line. You will, in all likelihood, need to make your FileIOHelper class described below. once you located your file you can stop executing and display the output of where the file was located. Create a class called FileIOHelper. This has two private String arrays, directories and files. It also includes two public instance int variables dirLength and fileLength witch stores length of directories and files String arrays respectively. it has one constructor that takes a file object, witch is used to determine the directory where you are going to be getting the information from. the constructor needs to iterate through each array element provided and assign the String to the right array(it's either a dir or file). Your arrays need to resize properly as you iterate through them. The fileIOHelper has two public methods, getDirectories() and getFiles() both return their respective protected String arrays. The FileIOHelper also has 2 private methods addToFile() and addToDirectory() witch both take a String and return a String array extra 1)keeping track of witch stack your working on currently - loggin information to a file through a static logger class. 2)using assertions where posible.

In my coding, ys, ms, ds represents year starting, month starting, starting day... ye, me, de represents end... start,end gives file names in the format of yyyymmdd now i want to process files from 20100101 to 20100930 means from date is 2010/01/01 and to date is 2010/09/30 if i press submit button the files from 20100101 to 20100930 are processes here ys=2010 ms=01 ds =01 and ye=2010 me=09 de= 30 For this how do i call these textbox values (from date text box and todate) to another program (java) Thanks in advance. Hello everyone. This is my first program. According to the idea of a program that calculates the sum of savings with the bank interest rates that is paid each year. And I put one amount every month. The question is very simple why full = 0? Code: var years = prompt("How many years will accumulate?)");
var prec = prompt("And how many % bank give?");
var income = prompt("How many you will put off in bank?");
var num = 12;
var full = 0;
months=years*num;
console.log("Altogether we get " + years + " years and " + months + " months.")
for (var month = 0; month == months; month++) {
if (month % num == 0) {
full = full + income + (full*prec/100);
} else {
full = full + income;
}
}
console.log("Total accumulated =" + full);

Try... Code: for (var month = 0; month<months; month++) {
Also note that your logic applies the full percentage at the 1st month of the loan/deposit. Is this what your really intended?

on this, Code: for (var month = 0; month<months; month++) {

Code: Altogether we get 2 years and 24 months. main.js:17 Total accumulated =2520 But if i write 1 year it dont work,how can i fix it? Code: Altogether we get 1 years and 12 months. main.js:17 Total accumulated =1200 Reply With Quote 01-24-2015, 09:42 PM #6 Old Pedant View Profile View Forum Posts Supreme Master coder! Join Date Feb 2009 Posts 28,310 Thanks 82 Thanked 4,754 Times in 4,716 Posts The value you get from a call to prompt() is *ALWAYS* a string. When you use the + operator with a string, it does *NOT* do addition; it does string concatenation. You just need to convert all those prompt() results to numbers: Code: var years = Number( prompt("How many years will accumulate?") );
var prec = Number( prompt("And how many % bank give?") );
var income = Number( prompt("How many you will put off in bank?") );
Also, you need to do Code: for (var month = 0; month <= months; month++) {
else you will only do (for example) up to month 23 when the user asks for 2 years. Be aware that prompt() and confirm() and console.log() are considered VERY obsolete and should only be used for debugging purposes, not for real web code. This is my code from prelim to finals. The missing part here is when the input is less than or equal to 65 and greater than 100, the prompt will say INVALID ENTRY. However, after it says Invalid Entry, it must ask you to enter again an Entry until you input a valid entry. It must be terminated after you input from prelim to finals either 0,20,30,40 or after you input a valid entry and after the program calculated it. My program does not terminate after I input valid entries. It just continue to ask grade again and again even it already calculated the grades. I don't know how will I put those code inside the program. I'm getting really confused. Code: <html>

Hello people CF, I need some help with this Javascipt program that im trying to make. Ill provide you with the algorithm i have made and the javascript code. I only know basic javascripting and i had a lot of help with this. I need help getting the javascript code for comparing last date modified, renaming the copied file with last date modified, also i can get it to copy 1 file, but i need it to loop through all the files in the given folder. Algorithm Code: // get source and destination folder path // check if folder exists // if source folder exists, continue with the process, otherwise display an error message // if destination folder exists, proceed with transferring the files // get the file collections in the source folder // loop through each file to check if the file has been modified // if the file exists, check file attributes to the source file; 32 means file has changed // if file has changed, // compare the last date modified of the source and destination file // if the source last date modified is greater than the destination last date modified then // rename the destination file by appending the last date modified // to its file name and then transfer the lastest file from the source folder // otherwise, no need to copy the file and move to the next file // otherwise, do nothing and move on to the next file // otherwise, create a folder first before proceeding with transferring the files I had a lot of help with this Code: <HTML>

I'm fairly new to writing programs in javascript and need a little help with this program. So far I have the following and need to write the program aspect for it. Thanks for taking a look for me. Code: document.writenln("Ragged or not<br />")
if (raggedOr(a))
document.writenln("Array is Ragged");
else
document.writenln("Array is not Ragged");
raggedOr was going to be the name of the function. <script type="text/javascript"> var myString = "zero one two three four"; var mySplitResult = myString.split(" "); for(i = 0; i < mySplitResult.length; i++){ document.write("<br /> Element " + i + " = " + mySplitResult[i]); } </script> "split" function splits the string whenever it encounters "space". But please explain me how the strings are stored in "mySplitResult". And can we use Arrays for this program? If so, can you code it. Thanks in advance! I'm very new at Javascript and writing programs so I'm not sure if this is even possible to do. I want to write a program that allows someone to select four tasks from a dropdown menu. The tasks are each 1 hour long. I want the program to calculate the number of hours and display that information below the tasks. I also want the person to be able to add or remove tasks. I get how to save tasks and display the results but I don't know how to calcuate the number of hours. Any suggestions? Here is what I have so far: Code: <!doctype html>

var taskDetail = document.getElementById(task).value;
localStorage.setItem(task, taskDetail);

}
function clearTask(task) {
localStorage.removeItem(task);
document.getElementById(task).value="";
}

outputResults = document.getElementById("Results");
outputResults.innerHTML =

Hi, I have to create a simple program in javascript (temperature converter) but without the use of functions. The other parameters in this are that: It creates a prompt asking the person if they want Fahrenheit -> Celsius or Celsius -> Fahrenheit It then has another prompt asking what temperature they'd like converted Finally, the output has both the original temperature and the converted one. Also it was noted that I had to use IF statement to guide the "flow of the program." I've been having a lot of troubles with it, as I do not know how to create a program without the use of functions. I'm also having issues with figuring out how to program it so the program knows that the user picked Fahrenheit to Celsius/Celsius to Fahrenheit and prompts them about the temperature they'd want changed. Any help/guiding would be great. Thanks. |
