Find output: Java operator-based queries (Part 1)

Query 1

package A1;
public class D {
 public static void main (String[] args) {
 for(int i=1;i<=3;)
 {
 for(int j=3;j>=1;)
 {
 if(i<=j)
 {
 System.out.println(i+" -- "+j);
 
}
 j--;
 
}
 i=i+2;
 }
 }
}

Query 2

package A1;
public class D {
 public static void main (String[] args) {
 for(int i=1;i<=3;)
 {
 for(int j=3;j>=1;)
 {
 if(i!=j)
 {
 System.out.println(i+" -- "+j);
 break;
 }
 j--;
 
}
 i=i+2;
 }
 }
}

Query 3

package A1;
public class D {
 public static void main(String[] args) {
 for (int i = 3; i <= 15;) {
 i += ++i + 2;
 System.out.println(i);
 ++i;
 }
 }
}

Query 4

package A1;
public class D {
 public static void main(String[] args) {
 for (int i = 3; i <= 15;) {
 i*= ++i + 2;
 i+=i;
 System.out.println(++i);
 }
 }
}

Query 5

package A1;
public class D {
 public static void main(String[] args) {
 int j = 3;
 for (int i = 3; i <= 9;) {
 i += i + j;
 j += i;
 j++;
 i = j;
 System.out.println(i + " " + j);
 }
 }
}
