My, your posts are difficult to read, because you hardly used any punctuation. Both of you. Do you mean, how do you change a .java file into something which has been compiled? That would be a .class file.
The Java™ Tutorials tell you how to do it. So does our "First Program" FAQ.
Remember you have to update your PATH as part of the installation process. If you haven't done this, you will have problems. If anything goes wrong, look at the "common problems" link at the bottom of the Java™ Tutorials page.
