创建一个Point类，有成员变量x，y，方法getX(),setX()，还有一个构造方 法初始化x和y。创建类主类A来测试它。

public class Point {
    private int x;
    private int y;
    public int getX() {
        return x;
    }
    public void setX(int x) {
        this.x = x;
    }
    public int getY() {
        return y;
    }
    public void setY(int y) {
        this.y = y;
    }
    public void Point() {
        
        this.x = x;
        this.y = y;
    }
    

}

package b;
import a.Point;
public class A {

    public static void main(String[] args) {
    Point shu=new Point();
    shu.setX(2);
    shu.setY(3);
    System.out.println("x="+shu.getX());
    System.out.println("y="+shu.getY());
    }

}
