}​

Answer 1

Answer:

3 5 6

Explanation:

public class MyClass {

   public static void main(String args[]) {

     int i=1;

       while(i++<=3)

       {

           i++;

           System.out.print(i+" ");

       }

       System.out.println(i);

   }

}

while checks 1<=3 (true) print (1++ => 2++ =>3)

while checks 3<=3 (true) print(3++ =>4++ => 5)

while checks 5<=3 (false) print(5++ => 6)
