In this article we will learn to implement a Java program that checks whether a given string is a palindrome or not. A Java program is provided below that reads a string, checks whether it is a palindrome or not. Program is as follows: import java.util.*; class Palindrome { void isPalindrome(String str) { String […]
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 try to implement a Java program to print prime numbers from 1 to n. A Java program is provided below that prompts the user for an integer and then prints out all prime numbers up to that integer. Program is as follows: import java.util.Scanner; class Prime { void primeGen(int […]
In this article we will learn to implement a Java program to print the nth element in the Fibonacci series. A Java program is provided below to print the nth element in the Fibonacci series using both non-recursive and recursive methods. Program is as follows: import java.util.*; class Fibonnaci { int nFib(int n) { […]
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 […]
