Question

I have a 2d array and I want to know how do you set the first value so if my array was

int array[a][b] = int[10][10];

How would you access index ‘a’ in a for loop?

This is my simple code that I am working on thanks in advance

int[][] timesTable = new int[12][12];

for(int i = 0; i < timesTable.length; i++){
    timesTable[i][i] = i + 1;//can't set the first index with this value
    System.out.println(timesTable[i]);
}

Answer 1

I hope you are not putting the “a” and “b” in the array declaration.

int array[][] = int[10][10];

A 2D array is array of arrays. The index “a” or what you are trying to set is another array.

 timesTable[i][i] = i + 1;//can't set the first index with this value

The above can be written like this:

timesTable[i] = {1,2,3};// puts another array at index i
