12.2.2 Parameterised Constructor
A parameterised constructor is a type of constructor with parameters and statements inside its body. Number of
parameters may be different depending on the number of instance variables. For example:
1 import java.util.*;
2 class rectangle1
3 {
4 int length,breadth,area, perimeter;
5 rectangle1(int l, int b)
6 {
7 length=l;
8 breadth=b;
9 }
10 void cal()
11 {
12 area = length * breadth;
13 perimeter = 2*(length+breadth);
14 }
15 void display ()
