The following compilation code issues an error: error: (15, 23) Java: not a statement in this line: for (j = 1, j & lt; = i; j ++; k ++)

The first for wrote correctly, and the second is not. Instead of , you need ; .

for (j = 1; j & lt; = i; j ++, k ++)
     {
       System.out.printLN (K + "");
     }
