Understand the following implementation which uses method or function overloading in Java

?class Addition{

??void add(int a,int b){

??System.out.println(Inside add(int,int) method);

???System.out.println(a+b);

???}

??void add(int a,int b,int c){

??System.out.println(Inside add(int,int,int) method);

???System.out.println(a+b+c);

???}

??void add(float a,float b){

??System.out.println(Inside add(float,float) method);

???System.out.println(a+b);

???} ??

?public static void main(String args[]){

? ?Addition obj=new Addition ();

? ?obj.sum(10,10,10);

? ?obj.sum(20,20);

? ?obj.add(10.5,10.5);

??}

?}

Output:

Inside add(int,int,int) method?

30

Inside add(int,int) method

40

Inside add(float,float) method?

21

Now predict the output of the program below. Also, state the advantages of function overloading

class Calculator{

??void sum(int a,long b){

System.out.println(Inside sum(int,long) method);

System.out.println(a+b);

}

??void sum(float a,long b){

???System.out.println(Inside sum(float,long) method);?

System.out.println(a+b);

}

??public static void main(String args[]){

?? ?Calculator obj=new Calculator ();

? ?obj.sum(20,20);

?? ?obj.sum(20.5,20);

??}

}
