java通訊錄

㈠ java：19.使用集合類工具實現一個名片通信錄。完成一個具有圖形界面的、功能比較完善的名片通信錄。

因為Vector已經實現了序列化，所以可以直接用對象流讀寫，寫了一個小例子 供參考

importjava.io.FileInputStream;
importjava.io.FileOutputStream;
importjava.io.ObjectInputStream;
importjava.io.ObjectOutputStream;
importjava.util.Vector;

publicclassoutStream{
	staticVector<String>v=newVector<String>();
	staticFilefdata=newFile("data");
	publicstaticvoidmain(String[]args){
		booleanflag=false;
		if(flag){
			for(inti=0;i<10;i++){
				v.add("name"+i);
			}
			saveVector();
		}
		
		if(!flag){
			readVector();
		}
	}
	privatestaticvoidsaveVector(){
		try{
			ObjectOutputStreamoos=newObjectOutputStream(newFileOutputStream(fdata));
			oos.writeObject(v);
			oos.close();
		}catch(Exceptione){
			e.printStackTrace();
		}
	}
	privatestaticvoidreadVector(){
		try{
			ObjectInputStreamois=newObjectInputStream(newFileInputStream(fdata));
			v=(Vector<String>)ois.readObject();
			ois.close();
			for(Stringe:v){
				System.out.println(e);
			}
		}catch(Exceptione){
			e.printStackTrace();
		}
	}
}

㈡ java小型通訊錄源代碼

package src;

public class TelBook {
// 姓名
String name;

// 家庭電話
Integer homePhone;

// 個人行動電話
Integer personalMobilePhone;

// 辦公電話
Integer officePhone;

// 家庭地址
String homeAddress;

// 辦公地址
String officeAddress;

// QQ號碼
Integer qqNumber;

// MSN號碼
String msn;

// 郵件
String email;

// 備注
String notes;

String getEmail() {
return email;
}

void setEmail(String email) {
this.email = email;
}

String getHomeAddress() {
return homeAddress;
}

void setHomeAddress(String homeAddress) {
this.homeAddress = homeAddress;
}

Integer getHomePhone() {
return homePhone;
}

void setHomePhone(Integer homePhone) {
this.homePhone = homePhone;
}

String getMsn() {
return msn;
}

void setMsn(String msn) {
this.msn = msn;
}

String getName() {
return name;
}

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

String getNotes() {
return notes;
}

void setNotes(String notes) {
this.notes = notes;
}

String getOfficeAddress() {
return officeAddress;
}

void setOfficeAddress(String officeAddress) {
this.officeAddress = officeAddress;
}

Integer getOfficePhone() {
return officePhone;
}

void setOfficePhone(Integer officePhone) {
this.officePhone = officePhone;
}

Integer getPersonalMobilePhone() {
return personalMobilePhone;
}

void setPersonalMobilePhone(Integer personalMobilePhone) {
this.personalMobilePhone = personalMobilePhone;
}

Integer getQqNumber() {
return qqNumber;
}

void setQqNumber(Integer qqNumber) {
this.qqNumber = qqNumber;
}

public TelBook() {

}

public TelBook(String name, Integer personalMobilePhone) {
this.setName(name);
this.setPersonalMobilePhone(personalMobilePhone);

}

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
TelBook myfriend = new TelBook("張三", new Integer("13800138000"));

}

}

㈢ 實現一個小型通訊錄。Java

Friend類：public class Friend {
/*
* 姓名
*/
private String name;
/*
* 電耐稿話
*/
private String telephone;
/*
* 郵箱
*/
private String email;
/*
* 公司
*/
private String company; public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public String getTelephone() {
return telephone;
} public void setTelephone(String telephone) {
this.telephone = telephone;
} public String getEmail() {
return email;
} public void setEmail(String email) {
this.email = email;
} public String getCompany() {
return company;
} public void setCompany(String company) {
this.company = company;
} public String toString() {
StringBuffer str = new StringBuffer(); str.append("姓名：" + name).append("\n");
str.append("電話：" + telephone).append("\n");
str.append("郵箱昌仿孝：" + email).append("\n");
str.append("公司：" + company).append("\n");
str.append("-----------------------------------------\n");
return str.toString();
}
}AddFriend類：public class AddFriend { /**
* 主方法 程序的入口
*/
public static void main(String[] args) {
List<Friend> friendList = new ArrayList<Friend>();
char isGo = 'Y';
int i = 0;
do {
Friend friend = new Friend();
System.out.println("請輸入第" + (i + 1) + "位朋友的姓名：");
InputStreamReader reader = new InputStreamReader(System.in);
String str = "";
try {
str = (new BufferedReader(reader)).readLine();
} catch (IOException e) {
e.printStackTrace();
}
friend.setName(str); System.out.println("請輸入第" + (i + 1) + "位朋友的電話："); try {
str = (new BufferedReader(reader)).readLine();
} catch (IOException e) {
e.printStackTrace();
}
if (str.matches("\\d*") && str.length() == 11) {// 判斷用戶輸入的電話是否符合標准
friend.setTelephone(str);
} else {
System.out.println("電話號碼輸入有誤，請重新輸入！");
continue;
} System.out.println("請輸入第" + (i + 1) + "位大孫朋友的郵箱："); try {
str = (new BufferedReader(reader)).readLine();
} catch (IOException e) {
e.printStackTrace();
}
friend.setEmail(str); System.out.println("請輸入第" + (i + 1) + "位朋友的公司："); try {
str = (new BufferedReader(reader)).readLine();
} catch (IOException e) {
e.printStackTrace();
}
friend.setCompany(str); friendList.add(friend); i++; System.out.println("是否繼續添加？(Y/N):");
String go = "";
try {
go = (new BufferedReader(reader)).readLine();
} catch (IOException e) {
e.printStackTrace();
}
isGo = go.charAt(0);
} while (isGo == 'Y' || isGo == 'y'); for (int j = 0; j < friendList.size(); j++) {
System.out.println(friendList.get(j).toString());
}
}
}
