display two dimensional array java

//this way u can print your array row by row

for (int i = 0; i < row; i++){
	for (int j = 0; j < column; j++){
        System.out.println(array[i][j]);
	}
}

//this way u can print your array column by column

for (int i = 0; i < column; i++){
	for (int j = 0; j < row; j++){
		System.out.println(array[i][j]);
	}
}

Java 2-dimensional Array

class MultidimensionalArray {
    public static void main(String[] args) {

        // create a 2d array
        int[][] a = {
            {1, 2, 3}, 
            {4, 5, 6, 9}, 
            {7}, 
        };
      
        // calculate the length of each row
        System.out.println("Length of row 1: " + a[0].length);
        System.out.println("Length of row 2: " + a[1].length);
        System.out.println("Length of row 3: " + a[2].length);
    }
}

multi dimensional array declaration in java

Syntax:
return_type [][]varible_name=new return_type[no_of_rows][no_of_columns];
int [][]a=new int[5][5];


Valid Declearation are following:
int [][]a=new int[5][5];
int []a[]=new int[5][5];
int [][]a[]=new int[5][5][5];
