Hints

Write class Rectangle above public class Main, without the word public.

The constructor uses this.width = width;

Solution explanation

The object keeps its own width and height, and its methods use them to calculate.

Show solution

import java.util.Scanner;

class Rectangle {
    int width, height;

    Rectangle(int width, int height) {
        this.width = width;
        this.height = height;
    }

    int area() {
        return width * height;
    }

    int perimeter() {
        return 2 * (width + height);
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        Rectangle r = new Rectangle(sc.nextInt(), sc.nextInt());
        System.out.println("Area: " + r.area());
        System.out.println("Perimeter: " + r.perimeter());
    }
}
