Running a Program

Python Java
A Python program can be run as a script from a command prompt, as follows:

> python helloworld.py

 

Syntax and type errors are caught at run time.

A Java application must first be compiled, as follows:

> javac HelloWorld.java

The byte code file can then be run as follows:

> java HelloWorld

Syntax and type errors are caught at compile time.  All other errors are caught at run time.
