Подскажите пожалуйста, как сделать, чтобы потоки синхронизировались по файлу
"fileWithAnAdress.txt"public class Main {
public static void main(String[] args) {
boolean delete1 = (new File("fileWithoutGarbage.txt")).delete();
Thread thread = new Thread(new CreateFileService());
thread.start();
Thread thread1 = new Thread(new ReadFileService());
thread1.start();
}
}
public class CreateFileService implements Runnable {
@Override
public void run() {
List<String> list = new ArrayList<>();
list.add("'С:\\WebServers\\home\\testsite\\www\\myfile1.txt'");
list.add("'С:\\WebServers\\home\\testsite\\www\\myfile2.txt'");
list.add("'С:\\WebServers\\home\\testsite\\www\\myfile3.txt'");
list.add("'С:\\WebServers\\home\\testsite\\www\\myfile4.txt'");
try {
BufferedWriter bw = new BufferedWriter(new FileWriter("fileWithAnAdress.txt"));
for (String s : list) {
bw.write(s);
bw.write(System.lineSeparator());
}
bw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
public class ReadFileService implements Runnable {
@Override
public void run() {
List<String> lines = new ArrayList<>();
List<String> newLines = new ArrayList<>();
try {
BufferedReader br = new BufferedReader(new FileReader("fileWithAnAdress.txt"));
String line;
while ((line = br.readLine()) != null) {
lines.add(line);
}
System.out.println(lines);
for (String s : lines) {
String newString = s.substring(s.lastIndexOf('\\') + 1, s.lastIndexOf('.'));
newLines.add(newString);
}
System.out.println(newLines);
} catch (IOException e) {
e.printStackTrace();
}
try (BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter("fileWithoutGarbage.txt"))) {
for (String newLine : newLines) {
bufferedWriter.write(newLine);
bufferedWriter.write(System.lineSeparator());
}
} catch (IOException e) {
e.printStackTrace();
}
File file = new File("fileWithoutGarbage.txt");
System.out.println(file.length() + " byte");
}
}
Простой
