In this Java items example, we declared a matrix of integer items. 6 a Java program to find the index of an array element. Read all elements for the matrix. Now that we have understood the procedure, let us write the code for the same. import java.util. So it prints all the way to the center correctly but then it repeats one or more elements. *; class GFG { static void print (int [] [] mat) { // Traverse through all rows for (int i = 0; i < mat.length; i++) { // If current row is even, print from // left to right if (i % 2 == 0) { Also, most importantly, you will learn how to print matrix in Z form. So, here we have reversed the array in the memory without using an auxiliary array. C++ #include <bits/stdc++.h> using namespace std; const int MAX = 100; Finally, we will print the sum of the matrices. Time Complexity: O(N*M) where N is the number of rows in the matrix and M is the number of columns in the matrix. Program: public class matrix{ public static void main(String args[]) { If isUp = 1 then start printing elements by incrementing column index and decrementing the row index. 2 commits. We can add, subtract and multiply matrices. 2) Java Program to subtract the two matrices. We have another better alternative deepToString () which is given in java.util.Arrays class. for each is also called as enhanced for loop. Example 2: Print an Array using standard library Arrays import java.util.Arrays; public class Array { public static void main(String [] args) { int[] array = {1, 2, 3, 4, 5}; System.out.println (Arrays.toString (array)); } } Output [1, 2, 3, 4, 5] Method: Java Program to Print the elements of the Matrix in Spiral Form By Static Initialization of Array Elements Approach: Initialize and declare a matrix.
