Java-31-2D Array in java

Two dimensional array's are represented using two pair of square brackets which denotes the two dimensions of the array.

2D Arrays are accessed by two index number or subscript inside the two square brackets.

Declaration of 2D array: int array[][];
We can declare the array with data type followed by array_name with two pairs of square brackets.
Creation Of Array: array= new int[3][4];
After declaration of array we can create the array using the new keyword and specifying the data type and size of the array.

Declaration & Creation : int student[][]= new int[10][10];
Declaration & Creation can be done at the same time.

Initialization of Array:
marks[0][0]=70;
marks[0][1]=50;
marks[1][2]=80;
Initialization of array can be done by specifying the index number inside the brackets.

Declaration & Initialization:
int myArray[][]= { {1,2,3}, {4,5,6} };
2D array initialization is done by grouping the rows with braces and separating them with commas(,).
