面相对象往一个数组里添加学生，显示学生信息

文件1：

public class Stu {
    String name;
    int age;
    int score;
}

文件2：

 public class T2 {
    Stu[] stus = new Stu[30];
    String[] name = new String[30];

    void addstu(Stu stu) {
        for (int i = 0; i < stus.length; i++) {
            if (stus[i] == null) {
                stus[i] = stu;
                break;
            }
        }

    }

    void show() {
        for (int i = 0; i < stus.length; i++) {
            if (stus[i]!= null) {
                System.out.println(stus[i].name+"\t"+stus[i].age+"\t"+stus[i].score);
            }else{
                break;
            }
        }
    }

    public static void main(String[] args) {
        T2 t2 = new T2();
        Stu stu1 = new Stu();
        stu1.name = "大王";
        stu1.age = 20;
        stu1.score = 60;
        Stu stu2 = new Stu();
        stu2.name = "小王";
        stu2.age = 18;
        stu2.score = 80;
        t2.addstu(stu1);
        t2.addstu(stu2);
        t2.show();
    }
}
