You can also use new try-with-resource block introduced in JDK 1.7, in this advantage is you don't need to worry about closing any resource which implements Closable Interface.
Then code will look like this:
try (PrintWriter out = new PrintWriter("output.txt"))
{
out.print("hello");
}
catch (FileNotFoundException e)
{
System.out.print("file not found");
e.printStackTrace();
}
