Two Dimensional Array in Java

Above example is a two dimensional array class. It has a main method. We are declaring the two dimensional array. As we know each dimension needs to be square brackets. We put two brackets to declare that it’s two dimensional and the name of the array is twoDimensional.

And we are separating each row by the comma. So that tells it’s the next row. Once the EmpID and EmpName gets initialized what we are going to do is we are going to have a loop that goes through each of the ids, names and then print. After running the program the output is as above.
