In the following Java code how can I combine the two "contains" methods into one method "boolean contains(Square b)"? The bolded section needs to be combined into one method.

import java.util.Scanner;

public class Square { private double x, y, length; public Square(double x, double y, double length) { this.x = x; this.y = y; this.length = length; }

public double area() { return length * length; }

public double perimeter() { return 4 * length; } public boolean intersects(Square b) { if (this.contains(b.x, b.y) || this.contains(b.x + b.length, b.y) || this.contains(b.x, b.y + b.length) || this.contains(b.x + b.length, b.y + b.length)) { return true; } if (b.contains(x, y) || b.contains(x + length, y) || b.contains(x, y + length) || b.contains(x + length, y + length)) { return true; } return false; }

public boolean contains(Square b) { if (this.contains(b.x, b.y) && this.contains(b.x + b.length, b.y) && this.contains(b.x, b.y + b.length) && this.contains(b.x + b.length, b.y + b.length)) { return true; } return false; } private boolean contains(double xx, double yy) { if (xx >= x && xx <= (x + length) && yy >= y && yy <= (y + length)) { return true; } return false; }

public void draw() { StdDraw.square(x + length / 2, y + length / 2, length / 2); }

public static void main(String[] args) { double x1 = Double.parseDouble(args[0]); double y1 = Double.parseDouble(args[1]); double len1 = Double.parseDouble(args[2]); Square square1 = new Square(x1, y1, len1); System.out.println("The area is " + square1.area()); System.out.println("The perimeter is " + square1.perimeter()); Scanner sc = new Scanner(System.in); System.out.print("Enter the upper-left coordinates and the length of a square: "); double x2 = sc.nextDouble(); double y2 = sc.nextDouble(); double len2 = sc.nextDouble(); Square square2 = new Square(x2, y2, len2); if (square2.intersects(square1)) { System.out.println("It intersects the first square."); } else { System.out.println("It does not intersect the first square."); } if (square2.contains(square1)) { System.out.println("It contains the first square."); } else { System.out.println("It does not contain the first square."); } square1.draw(); square2.draw(); } }
