PrintWriter truncates string when writing to file, why?

Question

I'm writing to a file using PrintWriter like this:

Gson g = new Gson();
Article article = g.fromJson(reader, Article.class);
String json = g.toJson(article);

PrintWriter out = new PrintWriter(new FileWriter(cacheFile.getAbsolutePath()));
out.print(json);

However, the string in json is truncated when I see it in the file. What could be the reason for that?

Answer 1

You need to close the PrintWriter using PrintWriter#close() method

Add

out.close();

Answer 2

It doesn't. You failed to close the file.
