根据你的疑问，你是不会写学生名字的数组，学生名字肯定是个字符串，所以学生名字的数组应该是 private String[] name; 把这个属性加到班级类里就可以。
但是我想没必要使用name的数组，使用Student集合就可以。


/**
 * 学生类
 */
public abstract class Student {
    private String name;
    private int age;
    private float chinese;
    private float english;
    private float math;
    private float phy;
    private float chim;
    private float art;
    private float music;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public float getChinese() {
        return chinese;
    }

    public void setChinese(float chinese) {
        this.chinese = chinese;
    }

    public float getEnglish() {
        return english;
    }

    public void setEnglish(float english) {
        this.english = english;
    }

    public float getMath() {
        return math;
    }

    public void setMath(float math) {
        this.math = math;
    }

    public float getPhy() {
        return phy;
    }

    public void setPhy(float phy) {
        this.phy = phy;
    }

    public float getChim() {
        return chim;
    }

    public void setChim(float chim) {
        this.chim = chim;
    }

    public float getArt() {
        return art;
    }

    public void setArt(float art) {
        this.art = art;
    }

    public float getMusic() {
        return music;
    }

    public void setMusic(float music) {
        this.music = music;
    }

    /**
     * 学习的抽象方法
     */
    public abstract void learn();

    /**
     * 重写toString用于打印学生信息
     */
    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

/**
 * 学霸
 */
public class StudiousStudent extends Student {
    @Override
    public void learn() {
        System.out.println("学霸学习中...");
    }
}

/**
 * 学渣
 */
public class LazyStudent extends Student {
    @Override
    public void learn() {
        System.out.println("学渣学习中...");
    }
}

/**
 * 普通学生
 */
public class NormalStudent extends Student {
    @Override
    public void learn() {
        System.out.println("普通学生学习中...");
    }
}

/**
 * 班级
 */
public class Class {
    /**
     * 学生的集合
     */
    private List<Student> students;

    public List<Student> getStudents() {
        return students;
    }

    public void setStudents(List<Student> students) {
        this.students = students;
    }
}

这个数组怎么写呀？我贴图了滴呀
