How to find the total value, average value, etc. of a two-dimensional array (multidimensional array)-java

In a two-dimensional array, declare two [] as [] [].


                int[][] score = {
                { 1, 2, 3, 4, 5 },          //Line 0
                { 10, 20, 30, 40, 50 },     //The first line
                { 100, 200, 300, 400, 500 } //2nd line
        System.out.println(score[0][0]);    //0th row, 0th column
        System.out.println(score[1][1]);    //1st row, 1st column
        System.out.println(score[2][3]);    //2nd row, 3 columns

	//Note that it starts at row 0, column 0

		int[][] array = {

		//Outputs all integer elements contained in the 2D array array in order
for(int i=0; i<array.length; i++) { //Array name.Get the number of elements in a column (vertical direction) by length
	for(int s=0; s<array[i].length; s++) { //Array name[i].Get the number of elements in a row (horizontal direction) by length
		System.out.println(array[i][s]); //array[Vertical][side]

Console results 1 2 3 4 10 20 30 40 50 60 1000 10000


		int sum = 0;
		for(int i=0; i<array.length; i++) {
			for(int s=0; s<array[i].length; s++) {
				sum += array[i][s];

Console results 11220


		int sum = 0;
		int count = 0;
		for(int i=0; i<array.length; i++) {
			for(int s=0; s<array[i].length; s++) {
				sum += array[i][s];

Console results 935
