WHAT IS A PROGRAMMING LANGUAGE AND OOP FOR BEGINNERS?

AN IMPORTANT REMINDER!

• When you learn Java, you will think it is so easy. But when you try to type a code, you will be blocked if you don’t practice enough. Self-study is essential in IT. It is more critical than Instructor.?

WHAT IS A PROGRAMMING LANGUAGE?

• In the beginning, we should understand what the programming language is. Programming language is a block of codes that is interpreted by computer systems. There are more than 300 different programming languages, but only a few of them are widely used. Some of the popular programming languages are JAVA, Javascript, Python, C, C++, C#, and SQL.

THE FLOW OF A PROGRAMMING LANGUAGE?

1. Type your code by using alphabetical characters and some symbols.?
2. SDK will convert them to zero and ones.?
3. Your machine will understand the meaning of zero and ones.?
4. According to the meaning, it will start to act.?

ASCII CODES

• Every character in a programming language has numeric values. Those

numeric values are called “Ascii Codes”. - https://www.asciitable.com/?

WHY JAVA?

1. Java is straightforward to learn but if you don’t practice you will not be able to type any code.
2. Any code in Java can work on every platform. (Mac, Windows, etc..)
3. There are many programming languages in the world. The most common ones are Java, Python, and C#. But among those, Java is one of the most popular ones in the WORLD. After learning Java, learning other languages will take a couple of weeks. WHY? Because the logic is ultimately the same just the syntax will be different.
4. Java is an Object Oriented Programming Language.?

WHAT IS OBJECT-ORIENTED PROGRAMMING?

Variables, Objects, Methods, and Classes are used to create an Application. An object is an important component of an application.

We can think of a car toy that is created using smaller Lego parts. In this example, Lego parts represent “Objects” and the toy represents “Application” in Java.

If you make the objects, classes, and methods perfect, your application will work perfectly.

When doing an application in Java, developers create perfect objects and then assign some tasks to them through typing codes. They do all tasks perfectly because they are perfect. That is, creating objects depends on developers. For this reason, while doing an app in OOP; assigning tasks and testing it is so easy.?

The benefit of Object-Oriented Programming is being reusable, extensible, and maintainable.

WHY USE OOP?

In Starbucks, employees have limited contributions because Starbucks is created by a good system. Even a kid can prepare perfect coffee. But in a more traditional restaurant-such as a Turkish coffee shop- if the cooker is perfect, the coffee will be perfect. Similarly, in real life, the procedural system is the best but in coding, OOP is the best, because it is possible to create a perfect object-oriented system by developers Better objects will do better tasks. Because of that, in Java, we prefer Object-Oriented Logic.?
