Difference between Java and Javac

Would like to understand the rationale behind this;

Why do we keep typing Javac Introductions.java before we type java Introductions?

Hi Fung,

javac command is the command to start the java coompiler (c at the end of the javac). After the compiler creates the byte code you can call the java command to start the compiled programm and give it the name of your compiled programm. So "java" command (without a c) starts a Java application. It does this by starting a Java runtime environment, loading a specified class, and calling that class's main method.

Hope this helps
