To find out the area of a triangle using class.
To find out the area of a triangle using class.
Methodology: At first we
have to declared a class outside of public class and inside of package .The
class name is area .In the class I have to declared a veriable .In this veriable
I have to take two parameter . I apply the law area of a triangle in a variable
that name is area .Hence in the main function I write the class name and a obj
and this new area () is the memory size of the object and assignes it .Then I
take input by user ,using Scanner input=new Scanner(System.in).And print the
result .
Source code :
import java.util.Scanner;
class area {
float a(int l,int h){
float area =(float )(0.5*l*h);
return area ;
}
}
public class AreaOfTriangleUsingClass {
public static void main(String[] args) {
area obj=new area () ;
Scanner input = new Scanner(System.in);
System.out.print("Enter the length :");
int x=input.nextInt();
System.out.print("Enter the hight :");
int y=input.nextInt();
System.out.println("Area of triangle is :"+obj.a(x,y));
}
}
