I am now trying out different types of Java loops for my 5-year salary comparison program. So far, I seem to be having problems with trying out a do-while loop. I use NetBeans to build my programs and when I write the do-while loop in there, it produces several errors that I don't know how to resolve. Maybe my wording sounds incorrect, but let's check it out below to see what needs to be rewritten:
do {
System.out.println("Enter the salary individual 1 got in year 1: ");
firstIndividualSalary[0] = scan.nextInt();
System.out.println("Enter the salary individual 2 got in year 1: ");
secondIndividualSalary[0] = scan.nextInt();
if (firstIndividualSalary[0] == secondIndividualSalary[0]) {
System.out.println("Error. Try again.");
areAllDifferent = false;
input.next();
}
else {
areAllDifferent = true;
}
while (!(areAllDifferent));
If a do-while loop isn't the right choice for making a user re-enter an answer until their input is correct, then please let me know if either while loops or for loops will make more sense in building a completely error-free program. I personally don't feel like a do-while loop might work at all. I just need to figure out how to make a user re-enter a couple of answers so they don't end up matching each other. And I need to figure out the same issue for calculating the total amounts of 2 individuals' 5-year salaries. I would appreciate it if you took a look at this and answered with some revision suggestions. Thanks.
