How to call a method in java

Answer 1

In Java, you call a method by specifying the method name followed by parentheses () and any required parameters inside the parentheses

public class Main {
    public static void main(String[] args) {
        sayHello();  // Method call without parameters
    }

    public static void sayHello() {
        System.out.println("Hello, World!");
    }
}

In this example, sayHello is a method defined in the Main class. It's called within the main method by writing sayHello().

If a method requires parameters, you would include the values for those parameters inside the parentheses during the call, like so:

public class Main {
    public static void main(String[] args) {
        greet("John");  // Method call with parameter
    }

    public static void greet(String name) {
        System.out.println("Hello, " + name + "!");
    }
}

In this second example, the greet method is called with the argument "John" which is passed as a parameter to the method.
