Question

how to do function overloading programs in java ​

Answer 1

Answer:

   Overloading by changing number of arguments. class MethodOverloading { private static void display(int a){ println("Arguments: " + a); } ...

   By changing the datatype of parameters. class MethodOverloading { // this method accepts int. private static void display(int a)

Answer 2

Using overloading write a program to calculate and print the area of a square, rectangle and circle.

class AreaOverload

{

double a;

void area(int side)

{

a=side*side;

System.out.println("Area of a square is :"+a);

}

void area(int len, int br)

{

a=len*br;

System.out.println("Area of a Rectangle is :"+a);

}

void area(double r)

{

a=3.14*r*r;

System.out.println("Area of a circle is :"+a);

}

public static void main(String args[ ] )

{

AreaOverload ar=new AreaOverload();

ar.area(3);

ar.area(4,6);

ar.area(3.5);

}

}
