I don't understand how the process is going, how these equations are calculated. 0 1 2 3 4 

5 6 7 8 9

10 11 12 13 14

 for(int row = 0; row < iLimit; row++) { / System.out.println(""); for(; col < (row+1)*jLimit; col++) { System.out.print(col + " "); x = col + 1; } The whole code : 

final int iLimit = 3;

final int jLimit = 5;

for(int i = 0; i < iLimit; i++) {

System.out.println("");

for(int j = 0; j < jLimit; j++)

System.out.print(j + " ");

}

System.out.println("\nThis is");

int x = 0, col = 0;

for(int row = 0; row < iLimit; row++) {

System.out.println("");

for(; col < (row+1)*jLimit; col++)

{ System.out.print(col + " ");

x = col + 1;

}

x = col + 1;

 }
