Java Program to Find Area of Square, Rectangle and Circle using Method Overloading

This is a Java Program to Find Area of Square, Rectangle and Circle using Method Overloading.

We declare three methods of same name but with different number of arguments or with different data types. Now when we call these methods using objects, corresponding methods will be called as per the number of arguments or their datatypes.

Here is the source code of the Java Program to Find Area of Square, Rectangle and Circle using Method Overloading. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
class OverloadDemo
```
```
{
```
```
    void area(float x)
```
```
    {
```

        System.out.println("the area of the square is "+Math.pow(x, 2)+" sq units");

```
    }
```
```
    void area(float x, float y)
```
```
    {
```

        System.out.println("the area of the rectangle is "+x*y+" sq units");

```
    }
```
```
    void area(double x)
```
```
    {
```
```
        double z = 3.14 * x * x;
```

        System.out.println("the area of the circle is "+z+" sq units");

```
    }
```
```
}
```
```
class Overload 
```
```
{
```

     public static void main(String args[])

```
	{
```

	   OverloadDemo ob = new OverloadDemo();

```
	   ob.area(5);
```
```
	   ob.area(11,12);
```
```
	   ob.area(2.5);
```
```
        }
```
```
}
```

Output:

$ javac OverloadDemo.java
$ java OverloadDemo
 
the area of the square is 25.0 sq units
the area of the rectangle is 132.0 sq units
the area of the circle is 19.625 sq units
