The transpose of a matrix is the one whose rows are columns of the original matrix, i.e. if A and B are two matrices such that the rows of the matrix B are the columns of the matrix A then Matrix B is said to be the transpose of Matrix A.To print the transpose of the given matrix −Create an empty matrix.Copy the contents of the original matrix to the new matrix such that elements in the [j][i] position of the original matrix should be copied to the [i][j] position of the new matrix.Print the new matrix.ExampleLive Demopublic class TransposeSample{ ...

Given an array of type Integer, write a Java program to find the odd and even numbers from that array. Those numbers which are completely divisible by 2 are called even numbers and if a number gives 1 as a remainder on dividing with 2 is known as odd number. Printing Odd and Even Number from an Array To print odd and even number from an array in Java, use the following ways − Using for Loop Using stream API Using for Loop In this approach, use the for ...

To add two matrices −Create an empty matrixAt each position in the new matrix, assign the sum of the values in the same position from the given two matrices i.e. if A[i][j] and B[i][j] are the two given matrices then, the value of c[i][j] should be A[i][j] + B[i][j]ExampleLive Demopublic class AddingTwoMatrices{    public static void main(String args[]){       int a[][]={{1,2,3},{4,5,6},{7,8,9}};       int b[][]={{1,1,1},{1,1,1},{1,1,1}};       int c[][]=new int[3][3];       for(int i = 0;i

To find the smallest element of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the 1st element of the array.ExampleLive Demopublic class SmallestNumberInAnArray {    public static void main(String args[]){       int temp, size;       int array[] = {10, 20, 25, 63, 96, 57};       size = array.length;       for(int i = 0; i
