[sravan953]

Try this, it should work:

class print_ascii
{
static void ascii()
{
    for(int j=1;j<=26;j++)
        {
            int n=65;
            for(int i=1;i<=j;i++)
                {
                    char a=(char)n;
                    System.out.print(a+" ");
                    n++;
                }
             System.out.println();
            }
        }
    }

Just before you print each letter, check to see if its greater than 'J', if it is, you can exit your program immediately (exit is a method in the System class)

class print_ascii
{
static void ascii()
{
    for(int j=1;j<=26;j++)
        {
            int n=65;
            for(int i=1;i<=j;i++)
                {
                    char a=(char)n;
                    System.out.print(a+" ");
                    n++;
                }
             System.out.println();
            }
        }
    }
