boolean isFile(): whether it is a file or not
boolean createNewFile(): creates a new file
static File createTempFile(String prefix, String suffix): Creates a temporary file

void deleteOnExit(): deletes files when the JVM stops
boolean exists(): Determine if a file exists
boolean renameTo(File dest): Re-modify the name
