Read MoreJava program to set title position
In this article, you'll learn how to position the title of a border in a Java Swing application using the setTitlePosition() method. We'll position the title above the border's top line by utilizing the TitledBorder.ABOVE_TOP constant. This technique is useful for customizing the appearance of your Swing components. To set title position, use the setTitlePosition() method in Java. Let’s say we have to position the title above the border's top line. For that, use the constant ABOVE_TOP for the border − setTitlePosition(TitledBorder.ABOVE_TOP); Steps to set title position Following are the steps to set title position in Java − ...

Read MoreJava program to count set bits in an integer
In this article, we are given an integer value and the task is to count the total number of set bits of the given integer. For this task, we need to convert the given value into its corresponding binary representation. The binary number of an integer value is represented as the combination of 0's and 1's. Here, the digit 1 is known as the Set bit in the terms of the computer. Problem Statement Write a program in Java to count set bits in an integer − Input int num = 10 Output binary representation = 1010 set bit ...
Read MoreJava Program to initialize a HashMap with Lambda Expressions
Initialization of a Java HashMap means creating an instance of the HashMap class and adding elements to it. The standard way to initialize a HashMap is by using the new keyword. However, we will use the lambda expression in this article. Lambda expressions are methods without any names. It was introduced with the release of Java8. And, HashMap is a class of Java Collection Framework that implements Map Interface. It stores its element in key-value pairs. The Key is an object that is used to retrieve value associated with it. Example 1 The following Java program explains how to initialize ...
Read MoreJava program to find the area of a square
Given a square whose length of all its sides are l, write a Java program to find its area. A square is a rectangle whose length and breadth are same. Therefore, area of this type of rectangle is the square of its length. To calculate the area of square in Java, you simply need to multiply the given length of square with the length itself and store the result in another variable. Java Program to Find The Area of a Square A Java program that illustrates how to find the area of the square is shown below − public class ...
Read MoreJava Program to Print the Months in Different Formats
In this article, we are going to use various approaches for formatting the months using different libraries of Java programming language. There are several ways to display months. Sometimes the months are written as numbers, sometimes the months are written in long form or they are written in short forms. Using java.time.Month In this approach, the months are printed by specifying the month number that starts from the number 1. For instance -> Month.of(1) will give JANUARY. Example In this Java program, we are printing all 12 months name. import java.time.Month; public class ShowMonth { ...
Read MoreJava program to find smallest of the three numbers using ternary operators
To find the smallest from three given numbers using ternary operator, create a temporary variable to store the result of first comparison operation between two numbers. Then, perform second comparison operation between the result of first operation (i.e. temp) and third number to get the final result. Let's understand the problem statement with an example − Example Scenario: Input: nums = 20, 35, 10; Output: res = 10 What is Ternary Operator? The conditional operator in Java is also known as the ternary operator. This operator consists of three operands and is used to evaluate Boolean expressions. The goal ...
