I just created this method for a 2D array but is throwing me an exception.

I want it to do this with a certain number of rows.

This is my method:

private void createTriangle() { //Initializing the array with 1 more than the size of the rows array = new int[rows][];

array[0] = new int[1];//declaring number of elements in row array[1] = new int[2];//declaring number of elements in row

array[0][0] = 1;// Store a 1 in the first column of the first row // Store a 1 in the first column of every from the second one on array[1][0] = 1; // Store a 1 in the last column of every row from the second one on array[1][1] = 1; for (int i = 2; i

for (int i = 2; i 1. Store a 1 in the first column of the first row 2. Store 1's in the first column and second columns of the second row 3. For each additional row, do: - Store 1's in the first and last columns For every other column, store the sum of the values in the previous row previous column and previous row, same column
