            }   
            else {
                System.out.println("The number " + num + " is E-ZUGI");

                num++;

please check do while loop syntax
//--------------------------
do {
     // statements
} while (expression);

---------------------//


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");



    }

you have misplaced a closing bracket before while:

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