I'm just starting to learn the Java language, and have a few simple questions.
I have installed jre6 and jre7 as well as jdk1.7.0_01 in a folder named Java and subfolders for the jre's.
I created a folder off the root named greetings and have Hello.java and have ran the javac command properly and then ran the java command with three arg and it worked fine.
My next level involves import java.io.*;
How does the application source know where to import the java.io*? I remember seeing something about setting the system.path somehow. Is that why my new source wouldn't find the import? what statement is needed to set the location of the runtime?
Thanx in advance for any assistance.
