Windows and spaces in the files/folders names (puke face here). See this article for Java installation, you will find there also how to set PATH for various OS

you do not set the path correctly ,for setting the path go to my coputer and right click on this then click on adavanced tab then click on environmental variable button add a new user by click on new button then enter the path and set the variable value to the bin folder in the jdk directory.

What you have used above will work, but you need to point to an existing Java source file. Try putting it on your Desktop and trying something like this:

C:\Program Files\Java\jdk1.7.0\bin>javac C:\Users\MyName\Desktop\HelloWorldApp.java

Adding the JDK to your system path is a more long-term solution, which would allow you to call javac directly from the same folder as your source code.
