BufferedWriter不打印

Question

我试图组织用户名和密码到插槽和假设用户名不是电子邮件，我把它作为一个密码。我必须把这些文件，但它不是打印。不过，它是在阅读。能帮我个忙吗？提前谢谢。

public class Core {

public static void main(String[] args) {

    FileReader in = null;
    BufferedReader br = null;

    BufferedWriter uOut = null;
    BufferedWriter pOut = null;

    try {

        in = new FileReader("src/input.txt");
        br = new BufferedReader(in);

        uOut = new BufferedWriter(new FileWriter("src/username.txt"));

        pOut = new BufferedWriter(new FileWriter("src/password.txt"));

        String line = br.readLine();
        while(line != null) {

            boolean migrated = true;

            if(line.contains(":")) {

                String[] split = line.split(":");
                String user = split[0];
                String pass = split[1];

                if(!(user.contains("@") && user.contains(".com"))) {
                    migrated = false;
                }

                if(migrated) {
                    uOut.write(user, 0, user.length());
                    uOut.newLine();

                    pOut.write(pass, 0, pass.length());
                    pOut.newLine();
                } else {
                    pOut.write(user, 0, user.length());
                    pOut.newLine();
                    pOut.write(pass, 0, pass.length());
                    pOut.newLine();
                }

                line = br.readLine();
                continue;
            }

            if(!(line.contains("@") && line.contains(".com"))) {
                pOut.write(line, 0, line.length());
                pOut.newLine();

                line = br.readLine();
                continue;
            } else {
                uOut.write(line, 0, line.length());
                uOut.newLine();

                line = br.readLine();
                continue;
            }

        }

    } catch(Exception ex) {

        ex.printStackTrace();

    } finally {

        if(br != null) try { br.close(); } catch(Exception ex) { }

        if(uOut != null) try { uOut.close(); } catch(Exception ex) { }

        if(pOut != null) try { pOut.close(); } catch(Exception ex) { }

    }

}

}

我还应该指出，我没有任何例外，也没有任何错误可以显示。

我用一个文件data.txt测试了您的代码

foo:bar
blarg:bletch
blahonga:baar

更改小的代码

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;

public class Main {

    public static void main(String[] args) {

        FileReader in = null;
        BufferedReader br = null;

        BufferedWriter uOut = null;
        BufferedWriter pOut = null;

        try {

            in = new FileReader("data.txt");
            br = new BufferedReader(in);

            uOut = new BufferedWriter(new FileWriter("username.txt"));

            pOut = new BufferedWriter(new FileWriter("password.txt"));

            String line = br.readLine();
            while (line != null) {

                boolean migrated = true;

                if (line.contains(":")) {

                    String[] split = line.split(":");
                    String user = split[0];
                    String pass = split[1];
                    if (user.contains("@") && user.contains(".com")) {
                        migrated = false;
                    }

                    if (migrated) {
                        uOut.write(user, 0, user.length());
                        uOut.newLine();

                        pOut.write(pass, 0, pass.length());
                        pOut.newLine();
                    } else {
                        pOut.write(user, 0, user.length());
                        pOut.newLine();
                        pOut.write(pass, 0, pass.length());
                        pOut.newLine();
                    }

                    line = br.readLine();
                    continue;
                }

                if (!(line.contains("@") && line.contains(".com"))) {
                    pOut.write(line, 0, line.length());
                    pOut.newLine();

                    line = br.readLine();
                    continue;
                } else {
                    uOut.write(line, 0, line.length());
                    uOut.newLine();

                    line = br.readLine();
                    continue;
                }

            }

        } catch (Exception ex) {

            ex.printStackTrace();

        } finally {

            if (br != null) try {
                br.close();
            } catch (Exception ex) {
            }

            if (uOut != null) try {
                uOut.close();
            } catch (Exception ex) {
            }

            if (pOut != null) try {
                pOut.close();
            } catch (Exception ex) {
            }

        }

    }
}

结果是两个文件：

username.txt

foo
blarg
blahonga

password.txt

bar
bletch
baar
