Insert the missing comma in 2.E, and I think you got it.

I think you will find the answer by reading theAPI for FileOutputStream.

I think Dirk means change:
OutputStream out = new FileOutputStream(new File(�file.txt�)true);

to

OutputStream out = new FileOutputStream(new File(�file.txt�), true);

in Question 2, E and this SCJP 1.2 answer will be correct.
