Compiling Java programs in command line

Question

Do I have to run set Class and Set ClassPath in Commandline every time for compiling Java programs with these commands

set class ="C:\Program Files\Java\jdk1.8.0_121\bin";  
set classpath="C:\Program Files\Java\jre1.8.0_121\lib\rt.jar"; 
C:\>Javac Test1.java
C:\>Java Test1

even I added up folder up to bin in environment variable for setting up the environment variable.If I do not run SET CLASS and SET CLASSPATH, I get an error Error: Could not find or load main class Test1

Please answer thanks.

What i would do is :

1) Add jdk path to PATH.
2) Create a folder with all my classes in , the cd to that folder "javac" every class and then "java" the one containing the "main" method.

You also need the path where your compiled class files are in your classpath!

You only included the tools.jar - but not your class file(s).

When compiling, you should only point to those JVM classes, but when running your application, your classes need to be found too!
