Java Files.write NoSuchFileException

Question

I'm trying to write some text to a file using Files.write() method.

byte[] contents = project.getCode().getBytes(StandardCharsets.UTF_8);  try {     Files.write(project.getFilePath(), contents, StandardOpenOption.CREATE); } catch (IOException ex) {     ex.printStackTrace();     return; } 

According to the API, if the file doesn't exist, it will be created and then written to.

However, I get this:

java.nio.file.NoSuchFileException: C:\Users\Administrator\Desktop\work\Default.txt     at sun.nio.fs.WindowsException.translateToIOException(Unknown Source)     at sun.nio.fs.WindowsException.rethrowAsIOException(Unknown Source)     at sun.nio.fs.WindowsException.rethrowAsIOException(Unknown Source)     at sun.nio.fs.WindowsFileSystemProvider.newByteChannel(Unknown Source)     at java.nio.file.spi.FileSystemProvider.newOutputStream(Unknown Source)     at java.nio.file.Files.newOutputStream(Unknown Source)     at java.nio.file.Files.write(Unknown Source) 

Am I missing something?

You should be able to create a file, but you can't create a directory. You may need to check the directory C:\Users\Administrator\Desktop\work exists first.

You can do

Path parentDir = project.getFilePath().getParent(); if (!Files.exists(parentDir))     Files.createDirectories(parentDir);
