In this article, we will learn to print the ASCII value of a particular character in Java. ASCII (American Standard Code for Information Interchange) is a standard encoding system that assigns a unique numeric value to characters like letters, digits, and symbols. We’ll explain the concept of ASCII, demonstrate how to retrieve and display ASCII values in Java and provide practical examples to help you understand and apply this concept effectively. What Is ASCII? ASCII is a character encoding standard where each character (letters, digits, and symbols) is assigned a numeric value. For instance − ... Read More

In this article, we will learn to find if a year is a leap year or not using Java. Finding whether a year is a leap or not is a bit tricky. We generally assume that if a year number is evenly divisible by 4 is a leap year. But it is not the only case. A year is a leap year if − It is evenly divisible by 100 If it is divisible by 100, then it should also be divisible by 400 Except this, all ... Read More

Any whole number which is greater than 1 and has only two factors i.e. 1 and the number itself, is called a prime number. Other than these two number it has no positive divisor. In this article, we will explain Java programs to print prime numbers between 1 to 100. Few examples of prime numbers are − 2, 3, 5, 7, 11 etc. Steps to Print Prime numbers below 100 Follow the steps below to print prime numbers below 100 in Java − Take integer variable, let's say "A" Divide the variable A with (A-1 to 2) If A ...

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

To find the 2nd 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 2nd 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

To find the largest 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 from the end of the array.ExampleLive Demopublic class ThirdLargestNumberInAnArray {    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
