3. Write a java program to find area of geometric figures (atleast 3) using method overloading.

import java.util.*;
import java.io.*;
import java.lang.*;
class geoFig
{
              double area(double r)
              {
              return(3.14*r*r); //Cicle
              }

              float area(float s)
              {
              return(s*s); //Square
              }
            

double area(double b,double h)
    {
           return(0.5*b*h); //Triangle
    }

}

class geoMain
{
        public static  void main(String arg[]) throws IOException
        {
            DataInputStream ob=new DataInputStream(System.in);
             geoFig g = new geoFig();
              System.out.println("enter double value for radius of circle");
             double r=Double.valueOf(ob.readLine()).doubleValue();
             System.out.println("area of circle="+g.area(r));
              System.out.println("enter float value for side of a square");
             float s=Float.valueOf(ob.readLine()).floatValue();
             System.out.println("area of square="+g.area(s));
     System.out.println("enter double value for base & height of triangle");
             double b1=Double.valueOf(ob.readLine()).doubleValue();
             double h=Double.valueOf(ob.readLine()).doubleValue();
             System.out.println("area of triangle="+g.area(b1,h));
    }
