怎样用Java编写一个Student类，包含name，math,english,physics成员变量，包含计算平均值（average)、总成绩（sum）的成员方法

• 参考如下：

public class Student {

    private String name;

    private double math;

    private double english;

    private double physics;

    public Student(String name, double math, double english, double physics) {
        this.name = name;
        this.math = math;
        this.english = english;
        this.physics = physics;
    }

    public double average() {
        return this.sum() / 3.0;
    }

    public double sum() {
        return math + english + physics;
    }
}

@AllArgsConstructor
@Data
public class Student {

  private String name;

  private Double math;

  private Double english;

  private Double physics;

  public Double sum(){
    return math + english + physics;
  }

  public Double average(){
    return sum() / 3;
  }
}

你好题主，你可以参考各位长辈的答案，综合考虑，应该会有更大的收获，欢迎及时反馈。

public class Student {
    // 成员变量
    private String name;
    private int math;
    private int english;
    private int physics;

    // 构造函数
    public Student(String name, int math, int english, int physics) {
        this.name = name;
        this.math = math;
        this.english = english;
        this.physics = physics;
    }

    // 成员方法
    // 计算平均值
    public double average() {
        return (math + english + physics) / 3.0;
    }

    // 计算总成绩
    public int sum() {
        return math + english + physics;
    }

}
