java中输入两个点,java中给定两个长方形的中心点、长度、宽度，怎么判断他们是包含关系还是相交关系，怎么编写代码，想了很久…...

Java codeimport java.awt.Point;

public class Main {

public static void main(String args[]){

RectangeDemo r1 = new RectangeDemo(new Point(1,2),5,5);

RectangeDemo r2 = new RectangeDemo(new Point(10,8),5,5);

checkRelation(r1,r2);

}

static class RectangeDemo{

Point center;

double width;

double height;

public RectangeDemo(Point point, int width, int height) {

this.center = point;

this.width = width;

this.height = height;

}

}

public static void checkRelation(RectangeDemo r1,RectangeDemo r2){

if(Math.abs(r1.center.x -r2.center.x) > r1.width + r2.width

&& Math.abs(r1.center.y -r2.center.y) > r1.height + r2.height ){

System.out.println("相离");

}

else if(Math.abs(r1.center.x - r2.center.x) < Math.abs(r1.width - r2.width)

&& Math.abs(r1.center.y -r2.center.y) > Math.abs(r1.height - r2.height)){

System.out.println("包含");

}

else{

System.out.println("相交");

}

}

}

------解决方案--------------------

纠正一下。sorry

|x1-x2|>(L1+L2)/2&&|y1 - y2|>(H1+H2)/2;相离。

|x1-x2|

其他情况相交。Java codeimport java.awt.Point;

public class Main {

public static void main(String args[]){

RectangeDemo r1 = new RectangeDemo(new Point(1,2),5,5);

RectangeDemo r2 = new RectangeDemo(new Point(10,8),5,5);

checkRelation(r1,r2);

}

static class RectangeDemo{

Point center;

double width;

double height;

public RectangeDemo(Point point, int width, int height) {

this.center = point;

this.width = width;

this.height = height;

}

}

public static void checkRelation(RectangeDemo r1,RectangeDemo r2){

if(Math.abs(r1.center.x -r2.center.x) > r1.width/2 + r2.width/2

&& Math.abs(r1.center.y -r2.center.y) > r1.height/2 + r2.height/2 ){

System.out.println("相离");

}

else if(Math.abs(r1.center.x - r2.center.x) < Math.abs(r1.width/2 - r2.width/2)

&& Math.abs(r1.center.y -r2.center.y) > Math.abs(r1.height/2 - r2.height/2)){

System.out.println("包含");

}

else{

System.out.println("相交");

}
