It should be "interpreted, threaded, and dynamic". You express the program in source files written in the Java programming language, compile the source to Java class files, and run the class files on a Java virtual machine.

As you can see in Figure , the Java virtual machine contains a class loader, which loads class files from both the program and the Java API.

Only those class files from the Java API that are actually needed by a running program are loaded into the virtual machine. The bytecodes are executed in an execution engine. Coding standard Java suggests set of coding standard to follow while writing java program.
