//Statement
}
Example: How to find the area of a rectangle using parameterized constructor in Java
import java.util.Scanner;
class Test {
int area;
Test(int l, int w) {
area = l * w;
}
void display() {
System.out.println("Area of rectangle is: " + area);
}
}
class Main {
public static void main(String args[]) {
int length, width;
Scanner sc = new Scanner(System.in);
System.out.print("Enter length of rectangle:");
length = sc.nextInt();
System.out.print("Enter width of rectangle:");
width = sc.nextInt();
Test t = new Test(length, width);
t.display();
}
}
Output:
Enter length of rectangle:12
Enter width of rectangle:3
Area of rectangle is: 36
