نوشتن متن درون یک فایل

 

try {
    // write string to a file
    Files.write(Paths.get("output.txt"), "Hey, there!".getBytes());

} catch (IOException ex) {
    ex.printStackTrace();
}

To specify a different character encoding other than the default UTF-8, you can do the following:

try {
    // create a string list
    List<String> contents = Collections.singletonList("Hey, there!");
    
    // write string to a file
    Files.write(Paths.get("output.txt"), contents,
            StandardCharsets.UTF_16);

} catch (IOException ex) {
    ex.printStackTrace();
}

To create a non-existing file or append the string to an existing one, use the following code snippet:

try {
    // create a string list
    List<String> contents = Collections.singletonList("Hey, there!");

    // write string to a file
    Files.write(Paths.get("output.txt"), contents,
            StandardCharsets.UTF_16,
            StandardOpenOption.CREATE,
            StandardOpenOption.APPEND);

} catch (IOException ex) {
    ex.printStackTrace();
}
