Setting Java Path

[bugger]

I have a basic question now.

How can I put Java in path?

I used to use Eclipse for compiling and running Java classes. I just formatted my disk and now I only have JDK with me. I can compile and run Java classes provided they are in C:\j2sdk1.4.2_15\bin folder. I want to compiie and run even if they are in some other folder/drive.

Please advice.

The first section (Common Error Messages on Microsoft Windows Systems) at the top of this page Lesson: Common Problems (and Their Solutions) has a link Update the PATH variable that may be helpful.

Thanks.
The link you mentioned was helpful. I had to set environment variable.
