实现学生学号,数学,语文,英语成绩录入

并且计算平均成绩,按照平均成绩高低输出信息

你可以改改!

//实现简单的学生信息输入输出和初步的成绩排序

public class Student {

private int id; //学号

private int mathScore; //数学成绩

private int chinScore; //语文成绩

private int foreScore; //外语成绩

public Student() {

id = 0;

mathScore = 0;

chinScore = 0;

foreScore = 0;

}

public Student(int newId, int newMathScore, int newChinSvore,

int newForeScore) {

id = newId;

mathScore = newMathScore;

chinScore = newChinSvore;

foreScore = newForeScore;

}

public double getAverageScore() { //求平均成绩

double averageScore = ((double) mathScore + chinScore + foreScore) / 3;

return averageScore;

}

public void output(Student student) { //输出对象的内容

System.out.println(" " + student.id + " " + student.mathScore +

" " + student.chinScore + " "

+ student.foreScore + " " +

student.getAverageScore());

}

public int max(Student a[], int n) { //Student类对象数组的前n项中的成绩最大值的索引

int position = 0;

for (int i = 1; i n; i++) {

if (a[i].getAverageScore() a[position].getAverageScore()) { //比较平均成绩

position = i;

}

}

return position;

}

public void selectSort(Student a[]) { //Student类对象数组的选择排序

for (int n = a.length; n 1; n--) {

int i = max(a, n);

Student temp = a[i];

a[i] = a[n - 1];

a[n - 1] = temp;

}

}

}

要求编写一个java程序,输入学生信息,并能保存与显示学生信息。

import java.util.ArrayList;

import java.util.Scanner;import com.sun.org.apache.xpath.internal.Arg;

public class Student {

//两个私有属性

private int no ;

private String name ;

//默认构造函数

public Student(){}

//带参构造函数

public Student(int no,String name){

this.no=no;

this.name=name;

}

//添加学生信息

public void addStudentInfo(ArrayList list){

String flag1="yes";

do{

Student student=new Student();

Scanner in =new Scanner(System.in);

System.out.println("请输入学生学号:");

student.setNo(in.nextInt());

System.out.println("请输入学生姓名:");

student.setName(in.next());

list.add(student);

System.out.println("是否继续添加学生信息(yes/no)?");

flag1=in.next();

} while(flag1.equals("yes"));

}

//读取学生信息

public void showStudentInfo(ArrayListStudent list){

System.out.println(" 学生no: "+" 学生name: ");

for(Student student:list){

System.out.println(" "+student.getNo()+" "+student.getName());

}

}

public int getNo() {

return no;

}

public void setNo(int no) {

this.no = no;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public static void main(String arg[]) {

ArrayListStudent studentList= new ArrayListStudent();

Student student= new Student();

Scanner inn= new Scanner(System.in);

while(true){

System.out.println("----------------- 欢迎使用学生管理系统------------------");

System.out.println("1.输入学生信息");

System.out.println("2.显示学生信息");

System.out.println("0.退出系统");

System.out.println("请选择....");

int nn= inn.nextInt();

switch (nn) {

case 1:

student.addStudentInfo(studentList);

break;

case 2:

System.out.println("学生信息如下:");

student.showStudentInfo(studentList);

break;

case 0:

System.exit(0);

System.out.println("系统退出!");

break;

default:

break;

}

}

} }

Java实现简单个人信息录入

import java.util.Scanner;

public class 个人信息 

{

public static void main(String[] args) 

{

System.out.println("\n\t\t==========简单的个人信息录入==========\n");

init();

}//初始化!

private static void init()

{

for (; ; )

{

System.out.println("请输入姓名:");

String a=Input.getName();

System.out.println("请输入年龄:");

int b=Input.getAge();

System.out.println("请输入学历:");

String c=Input.getEducation();

System.out.println("你输入的信息^_^\t名字:"+a+"     年龄:"+b+"     学历:"+c+"\n");

}

}

}

class Input

{

private static Scanner sc=new Scanner(System.in);

private Input(){}

static String getName()

{

String name=sc.next();

return name;

}

static int getAge()

{

int age=sc.nextInt();

return age;

}

static String getEducation()

{

String education=sc.next();

return education;

}

}
