Java Programming

Hi There,

I have a program that uses a number of threads, all trying to write to the same text file.
I am using

static BufferedWriter bw = new BufferedWriter(new FileWriter("c:\\temp\\mem.log"));

to write to mem.log file

The problem is that each thread is closing the stream, i.e. it calls:

bw.flush(); 
bw.close();

and when the next thread is trying to write to the same file, using the same bw object, the following exception is thrown:

java.io.IOException: Stream closed
	at java.io.BufferedWriter.ensureOpen(BufferedWriter.java(Inlined Compiled Code))
	at java.io.BufferedWriter.write(BufferedWriter.java(Compiled Code))
	at java.io.Writer.write(Writer.java(Compiled Code))
	at g.out.Game.writeMemoryToLog(Game.java:87)
	at g.out.Start.run(Start.java:59)
	at java.lang.Thread.run(Thread.java:568)

Does anyone know of a way to close the stream after the last thread has written to the file?

Thanks.
