Every time I try to use "javac" in the command thing, it tells me that it can't find it.?

There are two ways

1)Go to the folder where you installed JDK there will be a bin folder

keep your file in that folder and now run your program

2)Right click on My Computer

Advanced

Add new environment variable with the value as path of bin folder

But I would suggest you to use an IDE like Eclipse or NetBeans

You have to add the path to the jdk to your system's path environment variable.

If you install your jdk in c:\jdk, you should add c:\jdk\bin to your path variable, so that your system will be able to find the javac command.

Alternatively, use a IDE such as Eclipse or Netbean, all the necessary path will be set up for you.

I had the same problem at first when i began Java programming, I just kept on trying it over again until I got it right. Make sure you followed the right steps.

set the environment variables, then its work properly
