高分求两个简单的JAVA设计源代码
上面 wuzhikun12同学写的不错售卖电影票的java代码，但我想还不能运行，并且还不太完善。我给个能运行的：（注意：文件名为：Test.java)
//要实现对象间的比较，就必须实现Comparable接口，它里面有个compareTo方法
//Comparable最好使用泛型，这样，无论是速度还是代码量都会减少
@SuppressWarnings("unchecked")
class Student implements ComparableStudent{
private String studentNo; //学号
private String studentName; //姓名
private double englishScore; //英语成绩
private double computerScore; //计算机成绩
private double mathScore; //数学成绩
private double totalScore; //总成绩
//空构造函数
public Student() {}
//构造函数
public Student(String studentNo,String studentName,double englishSocre,double computerScore,double mathScore) {
this.studentNo = studentNo;
this.studentName = studentName;
this.englishScore = englishSocre;
this.computerScore = computerScore;
this.mathScore = mathScore;
}
//计算总成绩
public double sum() {
this.totalScore = englishScore+computerScore+mathScore;
return totalScore;
}
//计算评测成绩
public double testScore() {
return sum()/3;
}
//实现compareTO方法
@Override
public int compareTo(Student student) {
double studentTotal = student.getTotalScore();
return totalScore==studentTotal?0:(totalScorestudentTotal?1:-1);
}
//重写toString方法
public String toString(){
return "学号："+this.getStudentNo()+" 姓名："+this.getStudentName()+" 英语成绩："+this.getEnglishScore()+" 数学成绩："+this.getMathScore()+" 计算机成绩："+this.getComputerScore()+" 总成绩："+this.getTotalScore();
}
//重写equals方法
public boolean equals(Object obj) {
if(obj == null){
return false;
}
if(!(obj instanceof Student)){
return false;
}
Student student = (Student)obj;
if(this.studentNo.equals(student.getStudentName())) { //照现实来说，比较是不是同一个学生，应该只是看售卖电影票的java代码他的学号是不是相同
return true;
} else {
return false;
}
}
/*以下为get和set方法，我个人认为，totalScore的set的方法没必要要，因为它是由其它成绩计算出来的
在set方法中，没设置一次值，调用一次sum方法，即重新计算总成绩
*/
public String getStudentNo() {
return studentNo;
}
public void setStudentNo(String studentNo) {
this.studentNo = studentNo;
sum();
}
public String getStudentName() {
return studentName;
}
public void setStudentName(String studentName) {
this.studentName = studentName;
sum();
}
public double getEnglishScore() {
return englishScore;
}
public void setEnglishScore(double englishScore) {
this.englishScore = englishScore;
sum();
}
public double getComputerScore() {
return computerScore;
}
public void setComputerScore(double computerScore) {
this.computerScore = computerScore;
sum();
}
public double getMathScore() {
return mathScore;
}
public void setMathScore(double mathScore) {
this.mathScore = mathScore;
sum();
}
public double getTotalScore() {
return totalScore;
}
}
//Student子类学习委员类的实现
class StudentXW extends Student {
//重写父类Student的testScore()方法
@Override
public double testScore() {
return sum()/3+3;
}
public StudentXW() {}
//StudentXW的构造函数
public StudentXW(String studentNo,String studentName,double englishSocre,double computerScore,double mathScore) {
super(studentNo,studentName,englishSocre,computerScore,mathScore);
}
}
//Student子类班长类的实现
class StudentBZ extends Student {
//重写父类Student的testScore()方法
@Override
public double testScore() {
return sum()/3+5;
}
public StudentBZ() {}
//StudentXW的构造函数
public StudentBZ(String studentNo,String studentName,double englishSocre,double computerScore,double mathScore) {
super(studentNo,studentName,englishSocre,computerScore,mathScore);
}
}
//测试类
public class Test {
public static void main(String[] args) {
//生成若干个student类、StudentXW类、StudentBZ类
Student student1 = new Student("s001","张三",70.5,50,88.5);
Student student2 = new Student("s002","李四",88,65,88.5);
Student student3 = new Student("s003","王五",67,77,90);
StudentXW student4 = new StudentXW("s004","李六",99,88,99.5);
StudentBZ student5 = new StudentBZ("s005","朱漆",56,65.6,43.5);
Student[] students = {student1,student2,student3,student4,student5};
for(int i = 0 ; istudents.length; i++){
double avgScore = students[i].testScore();
System.out.println(students[i].getStudentName()+"学生的评测成绩为："+ avgScore+"分");
}
}
}
运行结果为：
张三学生的评测成绩为：69.66666666666667分
李四学生的评测成绩为：80.5分
王五学生的评测成绩为：78.0分
李六学生的评测成绩为：98.5分
朱漆学生的评测成绩为：60.03333333333333分

Q1: 电影院售票的求大虾们帮我做一个电影院售票系统（C#,java都行）CS或者BS结构都行 ，很急 请大虾们帮帮忙
这是我以前写售卖电影票的java代码的
#includestdio.h
#includestring.h
#define N 99 //票数容量
struct Date
{
int year;
int month;
int day;
};
struct Word
{
char movie[20]; //片名
struct Date time; //上映日期
int price; //票价
int spare; //剩余票数
}a[N],t;
void newticket(FILE *fp)
{
printf("片名售卖电影票的java代码：");
scanf(" %s",t.movie);
printf("日期：(例如 2014 1 25)\n");
scanf("%d%d%d",t.time.year,t.time.month,t.time.day);
printf("票价：");
scanf(" %d",t.price);
printf("剩余票数：");
scanf(" %d",t.spare);
if(t.spare!=0) //余票不为0
fprintf(fp,"%-20s %4d-%02d-%02d %3d %3d\n",t.movie,t.time.year,\
t.time.month,t.time.day,t.price,t.spare);
fclose(fp);
}
void look(FILE *fp)
{
int i,n=0;
// char ch;
fclose(fp);
fp=fopen("电影票.txt","r");
for(i=0;iN;i++)
{
fscanf(fp,"%s %d-%d-%d %d %d\n",a[i].movie,a[i].time.year,\
a[i].time.month,a[i].time.day,a[i].price,a[i].spare);

a[i].time.month,a[i].time.day,a[i].price,a[i].spare);
fclose(fp);
}
void menu()
{
printf("========电影票管理系统========\n");
printf("1.添加售票 2.余票查询\n0.退出程序\n");
printf("==============================\n");
printf("功能选项:");
}
int main()

FILE *fp;
char c;
while(1)

Q2: 利用java，如何锁定数组中的一个值，例如，购买电影票选座位，如何用java实现
这段代码逻辑不清楚
int[] number=new int[100]; 这个number表示什么？座位号，一共100个座位？
n 代表什么？
最好把你的想法说下，这样好帮助你
Q3: javaEE编程，项目用的是SSH三大框架，做的是购票系统，比如是电影票，如何处理多个人选择多一张票的现象
就返回票已经购完售卖电影票的java代码，然后刷新一下页面不就好售卖电影票的java代码了
Q4: JAVA试题，答案求助
导入 java。售卖电影票的java代码？售卖电影票的java代码？？.句子太长售卖电影票的java代码，请提供一个短售卖电影票的java代码的句子。？？？.{}///第二个问题是 systemtln。？？？.Print (
Q5: 用java实现卖电影票的程序,实现5个窗口同时售卖100张票.(用数组保存)
public class Yugi implements Runnable
{
@Override
public void run()
{
String name = Thread.currentThread().getName();
while(name.startsWith("窗口"))
{
if(tickets.length == 0)
{
stop();
break;
}
int num = (int) (Math.random() * tickets.length) + 1;
tickets = new int[tickets.length - num];
System.out.println(name + " 售出了 " + num + " 张票");
try
{
Thread.sleep(500);
}
catch(InterruptedException e)
{}
}
}
public synchronized void start()
{
for(int i = 0; i ts.length; i++)
{
Thread thread = ts[i];
if(thread == null)
{
thread = new Thread(this);
thread.setPriority(Thread.MIN_PRIORITY);
thread.setName("窗口" + (i + 1));
thread.start();
}
}
}
public synchronized void stop()
{
for(int i = 0; i ts.length; i++)
{
Thread thread = ts[i];
if(thread != null)
{
thread.interrupt();
}
thread = null;
}
notifyAll();
}
static int[] tickets = new int[100];
private static int WIN = 5;
Thread[] ts = new Thread[WIN];
public static void main(String[] args)
{
new Yugi().start();
}
}
