Try this, it should work:
java Syntax (Toggle Plain Text) 
  1. class print_ascii
  2. {
  3. static void ascii()
  4. {
  5.     for(int j=1;j<=26;j++)
  6.         {
  7.             int n=65;
  8.             for(int i=1;i<=j;i++)
  9.                 {
  10.                     char a=(char)n;
  11.                     System.out.print(a+" ");
  12.                     n++;
  13.                 }
  14.              System.out.println();
  15.             }
  16.         }
  17.     }

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)
