请教java编程问题！紧急！！！

[mxr]

最近选修了最基础的java编程，刚开始尝试中。。。这周要交的一个作业不太会，麻烦高手们帮帮我！！！

Erstellen Sie ein Telefonverzeichnis (2 Punkte)
a) mit einem Array für die Speicherung von folgenden Namen und Telefonnummern.

String daten="Name: Bastian Schweinsteiger Telefonnr: 21321231";
String daten1="Name: Michael Ballack Telefonnr: 4324234";
String daten2="Name: Lukas Podolski Telefonnr: 4324351";

b) Schreiben Sie eigene Methoden für das Hinzufügen, Löschen und Ausgeben der Daten.

c) Loeschen Sie Michael Ballack aus dem Array

下面是我自己写的，但怎么运行都不对，希望会的同学尽快帮我改正，或者写个新的！！！拜托拜托了！！非常紧急！
class Person {
String name;
int phone;
}
class PhoneBook{
static Person[] book;
static int nEntries=0;

static void enter (String name, int phone){
if (nEntries>=book.length)
Out.println("-- phone book full, entry " + name + "ignored");
else{
book[nEntries] = new Person();
book[nEntries].name = name;
book[nEntries].phone = phone;
nEntries++;
}
}
static int delete(String name){
int i=0;
while (i<nEntries && !name.equals(book[i].name))
i++;
if(i == nEntries)
return -1;
else {book[i].name=null;book[i].phone=0;
return 0;}
}

static void printBook(){
for(int i =0; i <book.length;i++)
Out.println("Name: "+book[i].name+" Phone number: "+book[i].phone);
}

public static void main (String[] arg) {
book = new Person[10];
In.open("Telefonverzeichnis.txt");
String name=In.readString();
int phone;
while (In.done()){
phone =In.readInt();
enter(name,phone);
name =In.readString();
}
In.close();
printBook();
Out.println();

name=In.readString();
phone=In.readInt();
enter(name,phone);
Out.println();
Out.println();

for(;;){
name = "Michael Ballack";
phone=delete(name);
if (phone== -1)
Out.println(name + "unknown!");
else
Out.println("Phone number of "+ name +" ist deleted!");
Out.println();
Out.println();
printBook();
Out.println();
Out.println();}
}
}

for(;;){
这里用了死讯欢乐。 我就不信不出错
Out.println();我这边出错！不知道你用的啥。。。code有些可以借鉴，而且写得挺简单的。。但是主程序里你要打开文件.txt什么的。。我这边用你的代码太多错误，花那个时间看你的错误还不如自己编个新的而且由于整个思维方式不是俺的，俺又失去java灵感了。。都是颇sql弄得

这个是整个代码既有添加和删除的methoden, 那个array俺设成的是类的数组。。
而且也删除了那个micheln 就是代码里可能有冗余码。。
2分能给你1，5或者1分。。靠至少都运行了啊。。。用这个代码的话你们老师不给你分。。我在家诅咒他

你下次回帖写德文或英文会不会更直接一些？。。。
