- Compile .java file -> .class file in bytecode
- How JVM can know where is this .class and execute it? -> ClassLoader's help

a ClassLoader locates the bytecodes for a Java class -> reads the bytecodes -> creates an instance of the java.lang.Class class. 
Makes the class available to the JVM for execution.

- The use case is Hot deployment. Use a custom ClassLoader to re-load class into a running application.
