public class JustPractice {

    public int points=0;

    public static void main(String args[]) {
        JustPractice ha = new JustPractice();
        ha.end();
        happy();
    }

    public void end() {
        this.points=100;
        System.out.println(points);
    }

    public static void happy() {
        JustPractice object = new JustPractice();
        System.out.println(object.points);
        return;
    }

}

以上是显示:

100
0

而它应该显示:

100
100
