{

    public static void main(String arg[])

    {

        int outer = 1;

        while(outer < 3)

        {

            int inner = 5; 

            while(inner < 8)

            {

                System.out.println(outer + "  " + inner);

                inner++;

            }

            outer++;

        }

    }

}

Output :

1 5

1 6

1 7

2 5

2 6

2 7

DESCRIPTION
Here outer loop is executed for values going from 1 till less than 3 i.e. 1 and 2. Similarly inner loop is executed from 5 till less than 8 i.e. 5, 6 and 7. So when outer is 1, inner will become 5, 6, and 7 and when outer is 2, then also inner will become 5, 6, and 7.
