问题描述

你好，有人可以帮助我！



我堆叠这个问题..我只想要查看 员工数据 。数据保存在我的记事本中，这是我的记事本中的内容。

Hi can someone help me !

I am stack with this problem.. All I want is that I want to view Employees Data. The Data was save in my Notepad and this is what is in my Notepad.

<br />
#Employee.txt

Employee:{Fullname="User", JobTitle="Guard", Age="31"}
Employee:{Fullname="SecondUser", JobTitle="Janitor", Age="32"}
Employee:{Fullname="Johnson", JobTitle="SysAd", Age="33"}

我可以显示所有t通过使用以下代码，数据在我的 Employee.txt 中：...

I can show all the data''s in my Employee.txt by having this code: ...

import java.io.*;
import java.util.*;

public class ReadEmployees {

    public static void main(String[] args) throws IOException {
        Scanner scan = new Scanner(System.in);
        BufferedReader readfile = null;
        File filename = new File("Employee.txt");
        try {
            readfile = new BufferedReader(new FileReader(filename));
            String line = readfile.readLine();
            do{
                line = readfile.readLine();
                if (line != null) {
                    String input = line;
                    String str = input.replaceAll("Employee:+|,+|}+|\\{+|\\''", "");
                    String finalstr = str.replaceAll("\\s","\n");
                    String[]parts = finalstr.split("\\=+|\n");
                        System.out.println(finalstr+"\n");
                }
            }while(line!=null);
            readfile.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这是程序的输出：

this is the output of the program:

run:
Fullname="User"
JobTitle="Guard"
Age="31"

Fullname="SecondUser"
JobTitle="Janitor"
Age="32"

Fullname="Johnson"
JobTitle="SysAd"
Age="33"

BUILD SUCCESSFUL (total time: 0 seconds)

>但我希望在我运行程序时它会要求输入 FullName 然后如果输入 FullName 它将在我的 Employee.txt 如果发现它将显示员工的数据。



我想要输出：

> But I want that when I run the program It will ask to enter a FullName then If a FullName is entered It will search in my Employee.txt and if found it will display the Data''s of the Employee.

I want to have this output:

run:
enter Fullname: User

"User"
//then it will search for the name and if found it will be displayed 
Fullname="User"
JobTitle="Guard"
Age="31"

BUILD SUCCESSFUL (total time: 0 seconds)

I am hoping and waiting for an answer. 
Thank You..
