Question

• Write the example code to describe overloading and submit here.
• You need to put comments for your code.
• You need to add at least one more overloaded method to the example code.

public class OverloadingExample {
public static void main(String[] args) {
OverloadingExample t = new OverloadingExample();
t.methodX(5,9,2.2);
t.methodX(5,9,"Hi");
t.methodX(5,9,2);
t.methodX(5,9);
}

public void methodX(int a){
System.out.println("This is the method X with 1 parameters!");
}

public void methodX(int a,int b){
System.out.println("This is the method X with 2 parameters!");
}

public void methodX(int a, int b, int c){
System.out.println("This is the method X with 3 parameters!");
}

public void methodX(int a, int b, double c){
System.out.println("This is the method X with 3 parameter but last is a double!");
}

public void methodX(int a, int b, String c){
System.out.println("This is the method X with 3 parameter but last is a string!");
}
}

• Put the outputs   (results after you run your code) at the end of your code as a multi-line comment.

• Don't forget to put your name and a short description of your code on the top on your code. java

Answer 1

Overloading occurs when two methods share the same name but declartions are different.Based on number of arguments and

type of parameters the overloading method can be invoked. Method return type is not involved.

code:

public class OverloadingExample {
   public static void main(String[] args) {
       OverloadingExample t = new OverloadingExample();
       t.methodX(5,9,2.2);
       t.methodX(5,9,"Hi");
       t.methodX(5,9,2);
       t.methodX(5,9);
       t.methodX(4,"overloading");             //new method
   }

   public void methodX(int a){
       System.out.println("This is the method X with 1 parameters!");
       System.out.println("a="+a);
   }

   public void methodX(int a,int b){
       System.out.println("This is the method X with 2 parameters!");
       System.out.println("a="+a+",b="+b);
   }

   public void methodX(int a, int b, int c){
       System.out.println("This is the method X with 3 parameters!");
       System.out.println("a="+a+",b="+b+",c="+c);
   }

   public void methodX(int a, int b, double c){
       System.out.println("This is the method X with 3 parameter but last is a double!");
       System.out.println("a="+a+",b="+b+",c="+c);
   }
   public void methodX(int a, int b, String c){
       System.out.println("This is the method X with 3 parameter but last is a string!");
       System.out.println("a="+a+",b="+b+",c="+c);
   }
   public void methodX(int a,String c){
       System.out.println("This is the new method X with 2 parameter but last is a string!"); //new method
       System.out.println("a="+a+",c="+c);
   }
}

Output:

/*

This is the method X with 3 parameter but last is a double!
a=5,b=9,c=2.2
This is the method X with 3 parameter but last is a string!
a=5,b=9,c=Hi
This is the method X with 3 parameters!
a=5,b=9,c=2
This is the method X with 2 parameters!
a=5,b=9
This is the new method X with 2 parameter but last is a string!
a=4,c =overloading
