Hai, I want to know the user who is currently logged in the machine.If possible post the code too,lets consider windows as the O.S.Now I want to get the user from java,where I customize the perferences for my aplication based on the user logged in.

<pre> System.out.println(System.getProperty("user.name"));</pre>
See the API for System.getProperties() for a list of other proerties you can access. Additional properties may be available on your system - this list is just the standard ones.

This works for me on Win2K:
System.getProperty("user.name")

Hi. it's working fine,but the problem is if the user is a guest it displays unknown.Is there anyway to identify the guest user too.

Seriously, if the system allows people to log in with no account or password, then you will have to ask them.

It is sorta covered in the JavaRanch Style Guide.
