Singleton and writing to a common file

[Artemesia Lakener]

This is a follow-up to my previous post about "thread safe and writing to a common file". I changed the code to include singleton. Here is sample

public class LogWriter {

private static LogWriter lw = new LogWriter();
private LogWriter() {}
public static synchronized LogWriter getLogWriter() {
if(lw == null) lw = new LogWriter();
return lw;
}

private synchronized writeLog() {
// open file
// write file
// close file
}
}


Does this work ? I guess in this case I don't need to put "synchronized" keyword for an "object" inside the "writeLog()" method, right ? This is because I ensure only one static global instance is created. Please help me verify it.

thanks lot.

Let's not have five different conversations about this, please. I'm closing this thread; follow-ups can go here. Thank you.
