本文介绍了一个简单的学生信息管理系统的设计实现。系统通过定义学生类来存储学生的ID、姓名及平均成绩，并通过具体实例演示了如何创建学生对象以及访问其属性。

package student;

public class students {
private int studentId;
private String studentName;
private double averageScore;
private static int nextId = 1;

public students(String name,double score) {
studentId = nextId;
nextId++;
studentName = name;
averageScore = score;
}

public students(String name){
this(name,0);
}

public students(){
this("",0);
}

public String toString(String name) {
return name;
}
public int getStudentId(){
return studentId;
}
public void setStudentId(int studentId){
this.studentId = studentId;
}
public String getStudentName(){
return studentName;
}
public void setStudentName(String studentName){
this.studentName = studentName;
}
public double getAverageScore(){
return averageScore;
}
public void setAverageScore(double averageScore){
this.averageScore = averageScore;
}
public static void main(String[] args) {

}

}

package student;

public class operate {
private students s1 = new students("zhangsan",10.77);
private students s2 = new students("lisi",11.44);
private students s3 = new students("wangwu",12.11);

public static void main(String[] args) {

operate op = new operate();

System.out.println(" Id " +op. s1.getStudentId() + " Name " + op.s1.getStudentName() + " Averagescore "
+ op.s1.getAverageScore());
System.out.println(" Id " + op.s2.getStudentId() + " Name " +op. s2.getStudentName() + " Averagescore "
+ op.s2.getAverageScore());
System.out.println(" Id " + op.s3.getStudentId() + " Name " +op. s3.getStudentName() + " Averagescore "
+ op.s3.getAverageScore());
}

}

package student;

public class collageStudent extends students{
private int courseNum;
private float creditHour;

public static void main(String[] args) {

}
