Java实现简单个人信息录入

数据库就要你自己建了.

这里有一个类

实现学生学号，数学，语文，英语成绩录入

并且计算平均成绩，按照平均成绩亏亮碰高低输出信息

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 + " "键宴

+ student.foreScore + " " +

student.getAverageScore())

}

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

int position = 0

for (int i = 1i <ni++) {

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.lengthn >1n--) {

int i = max(a, n)

Student temp = a[i]

a[i] = a[n - 1]

a[n - 1] = temp

}

}

}

package test

import java.util.Scanner  // Import the Scanner class

public class 档大肆Test{

public static void main(String[] args) {

Scanner myObj = new Scanner(System.in)  // Create a Scanner object

System.out.print("输入年龄行轿：")

String age= myObj.nextLine()  // Read user input

System.out.print("输入姓名：")

String name= myObj.nextLine()  // Read user input

//再写 地点。。。仿喊

System.out.println(name+" 你好，今年" + age+"岁")  // Output user input

}}
