FileWriter is not closed on exit

FileWriter sby_f = new FileWriter( f);
BufferedWriter sby_writer = new BufferedWriter(sby_f);
sby_writer.write("abc");
sby_writer.write("\n");
sby_writer.write("xyz");
sby_writer.close();

In this above code, FileWriter sby_f is not closed explicitly by code. I wanted to know if this is closed by sby_writer.close(); or it is still open. Please do reply.

You only need to close the outside wrapper object, the BufferedWriter. The tutorials will tell you this, and I recommend you have a look at them.

So you say that, the fileWriter is not closed in tat code..rite?

No, Fubarable said the opposite: if you close the wrapper the wrapped stream is closed by the wrapper. You could've read this all in the API documentation.

kind regards,
