Q2: java练习题求完整代码

按照题目要求编写java程序完整代码的用javaBean规范设计java程序完整代码的学生类Studentjava程序完整代码的Java程序如下

需要创建user.java.test包,把Student.java文件和Test.java文件放入包中,编译Student.java文件并且编译运行Test.java文件得到运行结果

Student.java文件代码如下

package user.java.test;

import java.io.Serializable;

public class Student implements Serializable{

private static final long serialVersionUID = 1L;

private String no;

private String name;

private double score;

public Student(){}

public Student(String no,String name,double score){

this.no=no;

this.name=name;

this.score=score;

}

public String getNo(){ return no;}

public void setNo(String no){ this.no=no;}

public String getName(){ return name;}

public void setName(String name){ this.name=name;}

public double getScore(){ return score;}

public void setScore(double score){ this.score=score;}

public String toString(){

return "学号:"+no+",姓名:"+name+",成绩:"+score;

}

public static double getAvg(Student[] sArray){

double sum=0,avg;

for(int i=0;isArray.length;i++){

sum=sum+sArray[i].getScore();

}

avg=sum/sArray.length;

return avg;

}

}

Test.java文件代码如下

package user.java.test;

public class Test{

public static void main(String[] args){

Student[] sArray=new Student[5];

sArray[0]=new Student("001","张三",89.5);

sArray[1]=new Student("002","李四",82.5);

sArray[2]=new Student("003","王五",93);

sArray[3]=new Student("004","赵六",73.5);

sArray[4]=new Student("005","孙七",66);

System.out.println("这些学生java程序完整代码的平均分:"+Student.getAvg(sArray));

for(int i=0;isArray.length;i++){

System.out.println(sArray[i].toString());

}

}

}
