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.

Internshalaques.java

public class Internshalaques {
	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) {
		{
			 Internshalaques ob = new Internshalaques();
			 ob.area(5);
			 ob.area(11,12);
			 ob.area(2.5);
		}
	}
