In this article we will learn to implement a Java program to reverse the array. A Java program is provided below which reverses an array in-place (without using extra memory). Following program reads an array of elements and reverses the array in place i.e., without using any temporary array: import java.util.Scanner; public class Driver […]
In this article we will learn to implement a Java program to find the maximum and minimum value of an array. A java program is provided below which reads array elements from the user and finds out the maximum, minimum elements in the array. Program is as follows: import java.util.Scanner; public class Driver { […]
In this article we will learn to implement a Java program for matrix multiplication and matrix transpose. A Java program is provided below to check the compatibility for multiplication, if compatible, multiplies two matrices and also finds its transpose. import java.util.Scanner; class Matrix { void matrixMul(int m, int n, int p, int q) { int[][] […]
In this article we will learn to implement sorting an array in Java. A Java program is provided below to read a list of numbers and sort them. I have used exchange sort to sort the array in ascending order. The program is as follows: import java.util.*; class Driver { static void printArray(int […]
In this post we are going to look at some very basic and frequently asked array programs in Java interviews . Different programs are written as separate functions in the class ArrayClass. These programs are restricted to integers. Following programs are available: Reading elements into an array Printing elements in an array Printing the sum of […]
