how panache handles abstract class in java
//interface declaration
interface Polygon_Shape {
void calculateArea(int length, int breadth);
}
//implement the interface
class Rectangle implements Polygon_Shape {
//implement the interface method
public void calculateArea(int length, int breadth) {
System.out.println("The area of the rectangle is " + (length * breadth));
}
}
class Main {
public static void main(String[] args) {
Rectangle rect = new Rectangle(); //declare a class object
rect.calculateArea(10, 20); //call the method
}
}
