Use function in a Class

class Paralelogram{
    double length;
    double breadth;
    void area(){
        System.out.print("The area is: ");
        System.out.println(length*breadth);
    }
}
public class Main{
    public static void main (String args[]){
        Paralelogram para1 = new Paralelogram();
        Paralelogram para2 = new Paralelogram();
        double area;
        para1.length=8.5;
        para1.breadth=7.5;
        para2.length=5;
        para2.breadth=3;
                para1.area();
                para2.area();

    }
}

The Output is Given Below:
The area is: 63.75
The area is: 15.0
