Example 1
class Rectangle {
int length;
int width;
Rectangle(int l, int b) {
length = l;
width = b;
}
void area(Rectangle r1) {
int areaORectangle = r1!length

#$stem!o%t!println(&'rea o Rectangle &
areaORectangle);
}}
class Rectangle*emo {
p%blic static void main(#tring args+) {
Rectangle r1
= new Rectangle(1-, .-);
r1!area(r1);
}}
O%tp%t o the program
Area of Rectangle : 200
