Question

package hw.loops.co.il;

import java.util.Scanner;

public class LoopsTargilMedium3 {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int num;

        do {
            System.out.println("Please enter a number:");
            num = input.nextInt();

            if (num%2==0) {
                System.out.println("The number " + num + " is ZUGI");
            }   
            else {
                System.out.println("The number " + num + " is E-ZUGI");

                num++;
            } while (num!=-1);
            System.out.println("loop stoped");
        }
    }
}

收到此错误:

Exception in thread "main" java.lang.Error:
Unresolved compilation problem:
    Syntax error, insert "while ( Expression ) ;" to complete DoStatement

您在 while 之前放错了右括号:

..
      } //<-- missing this
    }while (num!=-1);
                System.out.println("loop stoped");
...
