public class Looping {

    private String string="";


    public Looping() {

        for(int j=2 ; j<5 ; j++) {

            string= ""+j+" ";


            for(int i=1 ; i!=j+1 ; i++){

                string+=""+ j*i +" ";

            }

            

            System.out.println(string);

        }

    }

}

Main if you need it:

public static void main(String[] args) {

        Looping loop = new Looping();

    }

Oxano, we don't usually help people unless they show an effort.

If you are confused with nested loops you might want to look up a reference on how loops work. There is nothing special about a loop but a loop inside another loop.

There are some examples here: http://forum.codecal...p-examples.html
Nested for loops for C++

Sorry, being too friendly again ;)

It's fine! :)

i don't know java, but you would have something like this: in some kind of pseudo-code

for i = 2 to 4 do:
  print i + " "
  for j = 1 to 3 do:
    print i*j + " "
