write a class with the name area using function overloading that computes the area of parallelogram, rhombus and trapezium in java
Answers
Answer:
mate if this answer is correct please mark me brainliest
Explanation:
class JavaExample
{
void calculateArea(float x)
{
System.out.println("Area of the square: "+x*x+" sq units");
}
void calculateArea(float x, float y)
{
System.out.println("Area of the rectangle: "+x*y+" sq units");
}
void calculateArea(double r)
{
double area = 3.14*r*r;
System.out.println("Area of the circle: "+area+" sq units");
}
public static void main(String args[]){
JavaExample obj = new JavaExample();
/* This statement will call the first area() method
* because we are passing only one argument with
* the "f" suffix. f is used to denote the float numbers
*
*/
obj.calculateArea(6.1f);
/* This will call the second method because we are passing
* two arguments and only second method has two arguments
*/
obj.calculateArea(10,22);
/* This will call the second method because we have not suffixed
* the value with "f" when we do not suffix a float value with f
* then it is considered as type double.
*/
obj.calculateArea(6.1);
}
}
Output:
Area of the square: 37.21 sq units
Area of the rectangle: 220.0 sq units
Area of the circle: 116.8394 sq units
Question:-
➡Write a class with the name area using function overloading that computes the area of parallelogram, rhombus and trapezium in java.
Program:-
import java.util.*;
class Area
{
void area(int base, int height)
{
double a=0.5*base*height;
System.out.println("Area of the Parallelogram is: "+a);
}
void area(double d1, double d2)
{
double a=0.5*d1*d2;
System.out.println("Area of the Rhombus is: "+a);
}
void area(double h, double a, double b)
{
double A=0.5*h*(a+b);
System.out.println("Area of the trapezium is: "+A);
}
public static void main(String args[])
{
Area obj=new Area();
obj.area(2,3);
obj.area(20.0,50.0);
obj.area(10.0,20.0,20.0);
}
}
