HI i'm trying to loop this specific program with a yes/no question at the end of the program like:
" do you want to continue with the program yes/no "
please, really i will appreciate a lot your help

{
public static void main (String[] args)
{
double currentSalary;
double rating;
double raise;
System.out.print ("Enter the current salary: ");
currentSalary = Keyboard.readDouble();
System.out.print ("Enter the performance rating: ");
rating = Keyboard.readDouble();
if (rating==1);
raise = (currentSalary*0.06);
if (rating==2);
raise = (currentSalary*0.04);
if (rating==3);
raise = (currentSalary * 0.015);
System.out.println ("Amount of your raise: $" + raise);
System.out.println ("Your new salary: $" + (currentSalary + raise));
}
}

If you really want help, you will stop making new topics for the same question (that was answered), use code tags to post your source (there's a button "code"...) and try some things yourself. Now...
As a first step, you should put the functionality of your program (what you have in main) in a separate method, call it runOnce() of whatever you want.
Then, inside your main, you call this method in a do-while loop where you use another keyboard query to determine when to break out of it (you should also make a separate method for that). As a first step, Your program should look like this:
import cs1.Keyboard;
public class Salary {
public static void main (String[] args) {
do {
runOnce();
} while ( shouldContinue() );
}
private static void runOnce() {
double currentSalary;
//... (what you have in main)
//...
System.out.println ("Your new salary: $" + (currentSalary + raise));
}
private static boolean shouldContinue() {
//query the user like you ask for the current salary etc;
//you will want to read a char; your KeyBoard class probably has a method for that, so
//assuming you ask for 'y' or 'n'
if (userChoiceChar == 'y') {
return true;
} else {
return false;
}
}
}
Try this. If you run into a problem, post back with the exact code (in tags) and exact and full error message and someone will help you on.
