关于java#成员变量#的问题，如何解决？

为类中的私有成员变量提供对外访问（读和写）的方法
定义一个表示学生信息的Student 类，Student 类中定义表示学生姓名和成绩私有成员变量，并为Student 类对象提供对外读、写私有成员变量的方法。
例如设置对象的姓名为ZhanSan，成绩为98，输出结果为：The student ZhanSan's score is 98!

```java

```

public class Student {
    private String name ;
    private int score ;
    public String getName() {
        return name;
    }
    public int getScore() {
        return score;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void setScore(int score) {
        this.score = score;
    }
    public void show(){
        System.out.println("The student "+name+"'s score is "+score+"!");
    }
    public static void main(String[] args) {
        Student student=new Student();
        student.setName("ZhanSan");
        student.setScore(98);
        student.show();
    }
    

}

class test
{
    private String name;
    private int score;
    public test() {}
    public void setName(String n) {name = n;}
    public void setScore(int s) {s=score;}
    public String getName() {return name;}
    public int getScore() {return score;}
}
public class Untitled {
    public static void main(String[] args) {
        test t = new test();
        t.setName("ZhanSan");
        t.setScore(98);
        System.out.println("The student " + t.getName() + "'s score is " + t.getScore() + "!");}
    }
}

 
public class Student
{
    private String name;
    private int score;

    public void setName(String name) {this.name = name ;}
    public void setScore(int s) {this.score=score;}
    public String getName() {return this.name;}
    public int getScore() {return this.score;}
}
public class Test{
    public static void main(String[] args) {
        Student t = new Student();
        t.setName("ZhanSan");
        t.setScore(98);
        System.out.println("The student " + t.getName() + "'s score is " + t.getScore() + "!");}
    }
}
