Files.createFile(Path, FileAttribute<T>) - This method creates an empty file and throws an exception if the file already exist. You can also set the permission using the FileAttribute<T> which is optional.
================
class PracticingCreateFile{
public static void main(String[] args) throws IOException{
try{
String fileName = "TemporaryDocumentText.txt";
Path path = Paths.get(fileName);
if(Files.exist(path)){
throw FileAlreadyExistsException("This " + fileName + "does exist!");
}else {
Files.createFile(path)
System.out.println("This " + fileName + was created successfully.);
}
}catch(FileAlreadyExistsException f){
System.err.println(f.getMessage());
}
}
}
================
Result:
This TemporaryDocumentText.txt was created successfully.
Note: The first time you run, if file doesn't exist, it will create the file. The second time you run, it will throw the FileAlreadyExistsException.
