22L. Java Basics for Selenium - Java Arrays - Multi Dimensional Arrays

In this video we will see what are multidimensional arrays and how to declare them, how instantiate them and how to initiate them. We will also see how to loop over the multidimensional arrays.

Multidimensional Array:
Syntax:
• dataType[][] arrayRefVar;
• dataType [][]arrayRefVar;
• dataType arrayRefVar[][];
• dataType []arrayRefVar[];
Instantiating a Multidimensional Array:
int[][] testarray = new int[2][2];
Initializing Multidimensional Array:
testarray[0][0] = 1;
testarray[0][1] = 2;
testarray[1][0] = 3;
testarray[1][1] = 4;
You can define, instantiate and initialize a multidimensional array the following way.
Int[][] testarray = {{1,2},{3,4}};
