Java should be your first programming language

Today I was thinking that Java should be one of the first languages you should learn in order to understand OOP. One of the most common questions in a hiring process is "what is the difference between an abstract class and an interface?". If you have implemented them in Java, you can tell the difference. This also applies for other programming languages like C#. Sure, you can start with Python. However, I think that OOP concepts are better explained when using Java.

Pseudocode should be one’s first computing language - if one cannot describe the behavior as intended, one cannot assess as to whether a given implementation works as good or better than those intentions.
