? 按照所给的程序流程图，写出Java代码（用类和方法实现）

代码为：package com.lwk.test2;

主类：

import java.util.Scanner;

package com.lwk.test2;

public class Demo {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

Test test = new Test();

test.test();

}

}

方法类：

package com.lwk.test2;

import java.util.Scanner;

public class Test2{

    public  void test() {

       Scanner input = new Scanner(System.in);

       System.out.print("请输入x:");

       double x = input.nextDouble();

       System.out.print("请输入Y:");

       double y = input.nextDouble();

       if (x < 4 || y > 0) {

           if (y > 1) {

              y = y + 1;

              System.out.println("此时x=："+x+"y=:"+y);

              System.out.println("结束");

           } else {

              System.out.println("此时x=："+x+"y=:"+y);

              System.out.println("结束");

           }

       } else {

           if (x >= 5) {

              x = x - y;

              System.out.println("此时x=："+x+"y=:"+y);

              System.out.println("结束");

           } else {

              x = x + y;

              System.out.println("此时x=："+x+"y=:"+y);

              System.out.println("结束");

           }

       }

    }

}
