Benefits of Java static method

--Can be used without instantiation. --Since it is a method shared within the class, it can be accessed from other methods.

class TestClass {

    private TestClass(){

    //static method
    public static void printlnHelloWorld() {
        System.out.println("Hello World!");

Use of static methods

public class HelloWorld {
    public static void main(String[] args) {
        TestClass.printlnHelloWorld(); //No instantiation required
