Question

即使在提到'\'路径

之后，我也提到了跟踪错误

File file = new File("E:\\RConnect4s\\RConnect4s\\ZoneEast\\Utilities\\NBR.txt");

我的完整代码

public class UnixInterface implements Serializable {


String content = "This is the content to write into file";

/*File file = new File("E:\\RConnect4s\\RConnect4s\\ZoneEast\\Utilities\\NBR.txt");*/
File file = new File("E:\\RConnect4s\\RConnect4s\\ZoneEast\\Utilities\\NBR.txt");

    if (!file.exists()) {
    file.createNewFile();
}

FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(content);
bw.close();

System.out.println("Done");

}

您的代码工作正常，请参阅your Code

有关详细信息，请参阅Java Doc

更新：在您的代码中，您只能在类级别进行初始化，因此请尝试在以下任何函数内执行操作：

public class UnixInterface implements Serializable {

  public static void main(String[] args) {
     String content = "This is the content to write into file";    
      /*File file = new File("E:\\RConnect4s\\RConnect4s\\ZoneEast\\Utilities\\NBR.txt");*/
      File file = new File("E:\\RConnect4s\\RConnect4s\\ZoneEast\\Utilities\\NBR.txt");

       if (!file.exists()) {
           file.createNewFile();
       }  

      FileWriter fw = new FileWriter(file.getAbsoluteFile());
      BufferedWriter bw = new BufferedWriter(fw);
      bw.write(content);
      bw.close();    
      System.out.println("Done");
   }
}

此代码也有效，请参阅your code 2

我的java代码中的转义序列无效（有效转义序列是\ b \ t \ n \ f \ r \“\'\\）错误？
