一道java题
请设计一个学生类Student。属性包括：学号、姓名、英语成绩、数学成绩、计算机成绩、总成绩。方法包括：构造方法、compare方法（比较两个学生的总成绩，结果分大于、小于、等于），sum方法（计算总成绩）、testScore方法（计算评测成绩，可以取三门课成绩的平均分）。
老师布置的作业，求求各位大神了！ 展开

public class Student
{
private String stuId;
private String name;
private float englishScore;
private float mathScore;
private float computerScore;
private float sumScore;
public Student()
{
}
public Student(String stuId, String name, float englishScore,
float mathScore, float computerScore)
{
this.stuId = stuId;
this.name = name;
this.englishScore = englishScore;
this.mathScore = mathScore;
this.computerScore = computerScore;
this.sumScore = sum();
}
public String getStuId()
{
return stuId;
}
public void setStuId(String stuId)
{
this.stuId = stuId;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public float sum()
{
return sumScore = englishScore + mathScore + computerScore;
}
public float testScore()
{
return sum()/3;
}
public String compare(Student student)
{
if(this.sumScore > student.sum())
return "大于";
else if(this.sumScore == student.sum())
return "等于";
else return "小于";
}
public static void main(String[] args)
{
Student tim = new Student("0001", "tim", 90, 90, 90);
Student tom = new Student("0001", "tom", 80, 90, 95);
System.out.println("tim的测评成绩："+tim.testScore());
System.out.println("tom的测评成绩："+tom.testScore());
System.out.println("tim总成绩 "+tim.compare(tom)+" tom总成绩");
}
}
上面的代码作为作业应该够用了，如果应用最好重写equals和hashCo方法。
