Question

Class Main {

Answer 1

Answer:

class Main {

 static void printPowers(int howMany, int nrRows) {

   for(int n=1; n<=nrRows; n++) {

     for(int power = 1; power<=howMany; power++) {

       System.out.printf("%d ", (int) Math.pow(n, power));

     }

     System.out.println();

   }

 }

 public static void main(String[] args) {

   printPowers(3, 5);

 }

}

class Main {

 static void printPowers(int howMany, int nrRows) {

   int n = 1;

   do {

     int power = 1;

     do {

       System.out.printf("%d ", (int) Math.pow(n, power));

       power++;

     } while (power <= howMany);

     System.out.println();

     n++;

   } while (n <= nrRows);

 }

 public static void main(String[] args) {

   printPowers(3, 5);

 }

}

Explanation:

The for loop gives the cleanest, shortest code.
