Methods Overloading in Java

Example of Void method

/*When we don't want our method to return anything, we use void as the return type*/
public class Methods {static void telljoke(){
        System.out.println("Hello It's a joke!");
    }

    public static void main(String[] args) {
        telljoke();
    }
}
Output: Hello Its a joke!

Method Overloading

public class Methods {
    static void foo() {
        System.out.println("Good Morning Bro!");
    }
    static void foo(int a) {
        System.out.println("Good Morning " + a + " Bro");
    }
    static void foo(int a, int b){
        System.out.println("Good morning " + a +" "+ b+ " Bro");
    }

    public static void main(String[] args) {
        foo();
        foo(100);
        foo(200,300);                                          
//Method overloading can't be performed by changing the return type of methods. 
    }
}
Output: Good Morning Bro!
        Good Morning 100 Bro
        Good morning 200 300 Bro
