c语言将学生id和成绩记录在文本文件"score.txt"中,从文件中读取学生信息和分数，求出平均分后升序写入另一个文件。...

Student类，代码如下：

package student;

import java.text.DecimalFormat;

public class Student {

private int id;//学号

private String name;//姓名

private int score1;//成绩1

private int score2;//成绩1

private int score3;//成绩1

private double avg;//平均值

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getScore1() {

return score1;

}

public void setScore1(int score1) {

this.score1 = score1;

}

public int getScore2() {

return score2;

}

public void setScore2(int score2) {

this.score2 = score2;
