用java编写的关于学生成绩统计系统的源代码

public class student implements Comparable<student>{

	public student(int ID,double grade,String name){
		this.ID=ID;
		this.grade=grade;
		this.name=name;
	}
	
	public void setName(String name){
		this.name=name;
	}
	
	public void setID(int ID){
		this.ID=ID;
	}
	
	public void setGrade(double grade){
		this.grade=grade;
	}
	
	public String getName(){
	   return name;    
	}
	
	public int getID(){
		return ID;
	}
	
	public double getGrade(){
		return grade;
	}
	
	public int compareTo(student object){     //用于在Classe类里面排序
		if(grade>object.grade)
		return 1;
		if(grade<object.grade)
		return -1;
		return 0;
		
	}
	 private int ID; //学号
	 private double grade;//分数
	 private String name;//名字
}
