It will throw a FileNotFoundException
if the file doesn’t exist and cannot be created (doc), but it will create it if it can. To be sure you probably should first test that the file exists before you create the FileOutputStream
(and create with createNewFile()
if it doesn’t):
File yourFile = new File("score.txt");
yourFile.createNewFile(); // if file already exists will do nothing
FileOutputStream oFile = new FileOutputStream(yourFile, false);
