Java, Python and C# Cheat Sheet

At the end of this post, you will find three cheat sheets. A Java, C# and a Python Cheat Sheet and the other one for C#. When you download the files, you will see the most common constructs of each language used in Object-Oriented Programming.

Notice that in these cheat sheets, you will find only a few constructs. The reason is that the intended goal is to be practical. You won’t want to be lost in 15 pages searching for a simple structure.

Java Cheat Sheet for OOP

Learning programming is difficult because students must learn a wide variety of topics at the same time. Such as Algorithms, Computational Models, Programming Languages Structures and Syntax, etc.

C# Cheat Sheet for OOP

Programming Learning

Several programming courses start by teaching a specific programming language.

However, the core skills to be learned by a beginner is not the programming language, but the paradigm. In other words, beginners need to learn first the paradigm, how to create computational models, how to create algorithms and, in general, how to solve problems using computational thinking.

Only after that, a student or learner can then focus on learning one specific programming language.

Syntax

Even though the more difficult part of learning programming is to learn the paradigm and to get the ability to solve problems using computational models, learning a new (programming) language also introduces another level of difficulty.

That’s the reason why I’m sharing with you these cheat sheets.

So, you don’t need to spend time memorizing (or “googling”) the syntax of the programming language, nor getting stuck on understanding a code in a different programming language than the one you are learning.

I recommend you print the files and have them when you are coding.

H@ppy coding!
