How to write data to file Java ME cldc 1.1 midp 2.0

I newly in java me, please help me.

I make project in NetBeans 7.0.1. and use cldc 1.1 midp 2.0.

I want to write data to the file.

How can I do it?

I try to use FileOutputStream. But it don't exists in java.io

NetBeans shows me only this list of classes and interfaces in java.io:
ByteArrayInputStream, ByteArrayOutputStream, DataInput, DataInputStream, DataOutput, DataOutputStream, InputStream, InputStreamReader, OutputStream, OutputStreamWriter, PrintStream, Reader, Writer.

Why it so short?

And how I can write data to file?

Data can be array of bytes (byte[]) or Object it better.
