How do i get Java commands to be recognized in command prompt?

I would like to do some of my Java programming homework at home, and when i type things such as "javac" & "java" it does not recognize it. How do i set it up so it recognizes Java coding?

You should set your environment so that the command interpreter (the shell) will be able to find the appropriate commands. This is something platform dependent, but most of the time what you need to do is to add the path of the java binaries to the PATH environment variable. For example, if your java binaries (java, javac) where installed in /home/anna/java/bin, you add the path to the PATH environment variable like this:

PATH=$PATH:/home/anna/java/bin

you can type this command directly into the command line, but this way it will be valid only for the current shell, so you´d better put this command into one of your shell´s initialization files (like $HOME/.bashrc or $HOME/.bash_profile if your shell is GNU Bash, for example).
