"javac" is not recognized as an internal or external command

Question

I need to convert my Matlab algorithm to Java. To do this, I use the toolbar java toolbar, after completing all the necessary steps, the assembly fails and this error is displayed:

'javac' is not recognized as an internal or external command, operating program, or batch file. Error: An error occurred during shelling in javac (error code = 1). Failed to create executable file.

When you type java -versionmatlab at the command prompt, this is what I get:

Java 1.6.0_12-b04 with Sun Microsystems Inc. Java HotSpot (TM) Client Mixed Mode VM

This means that I have to have this java compiler installed on my computer, only then the matlab java developer works. I'm new to Java, I'm not sure which compiler I should look for.
