Quit in a loop....

Question

Okay I have searched all over this forum for an answer to this but I can't seem to find the answer. Here is my assignment:
1) Ask the user for a value for side or to exit.
2) Read answer.
3) If user wants to exit, then quit.
4) Otherwise, change the Square object's side value.
5) Display Square's side, perimeter, and area values.
6) Return to step 1.
I have the beginning of the if statement here:
public class SquareTest {
public static void main(String args[])
Scanner input = new Scanner(System.in);
Square square1 = new Square();
  System.out.printf("Please enter a length or -1 to quit: ");
  int theSide = input.nextInt();
  if (theSide != -1);
   square1.setSide(theSide);
   System.out.println();
   System.out.printf("The length of a side of the square is: %d\n", square1.getSide());
   System.out.printf("The perimeter of the square is: %d\n", square1.perimeter());
   System.out.printf("The area of the square is: %d\n", square1.area());
  else
}But I cannot seem to figure out what to put in the else statement to make it quit. Also I am assuming that this will not re-loop back to the beginning, so any HINTS on that would be wonderful! Thank you in advance!

Answer 1

import java.util.*;
public class SquareTest {
    public static void main(String[] args) {
        String message = "Please enter a length or -1 to quit: ";
        Scanner input = new Scanner(System.in);
        int side;
        System.out.println(message);
        while ((side = input.nextInt()) != -1) {
            Square square = new Square(side);
            System.out.println(message);
}Look Ma, no breaks!
