IT professions have been at the top of the high-paying professions for several decades. Most people think that you need a 5-year university degree to master this profession. But that’s not the case.
Moreover, many students in an effort to master it, combine university studies with learning programming, and do it on their own. It’s not surprising, because a student’s budget is limited and often, instead of courses, students save up for an essay writing service in order to get good grades.
Now we will tell you how you can also save money and become a programmer in six months on your own.
There are several programming languages. One of the most popular is Java.
It’s great for beginners for several reasons:
Java is an object-oriented programming language with strict typing.
Applications written in this language are easy to run from any platform, as long as JRE – Java Runtime Environment – is installed on the platform. This is possible due to the compilation of the Java code into byte-code. This function is performed by a virtual machine, JVM, which is part of the Java Runtime Environment and is platform-independent.
The language uses the garbage collector mechanism, which performs the memory management function. It automatically clears the memory and deletes objects that are no longer in use.
Java’s syntax is similar to other C-like languages. Its features are, for instance, case-sensitive.
It is advisable to start any learning process by setting clear goals. You need to understand why you need the knowledge and what you want to do with it.
Next, decide how you want to learn:
Another important step is to make a timetable. Firstly, you need to understand how many hours a day you will devote to learning. Secondly, at least roughly specify in what time frame and what topics you want to learn.
Another point: to successfully master this programming language, just like any other, it is important to maintain a balance between theory and practice. Without the practical day-to-day application of knowledge, your learning might take a long time. Moreover, the recommended ratio of theory to practice is 20% to 80% per day.
To simplify the work of programmers, class libraries have been created, which are needed to implement the most common tasks.
Classes can be:
Built-in classes are classes that are plugged in automatically (e.g., java. lang). Built-in classes are classes for solving system tasks and security system functioning, as well as class libraries for exception handling. Other libraries need to be included by themselves using the import operator.
Substitute classes are needed to convert the basic data types, e.g. char (basic) – Character (substitute).
To master the language, you also need to understand:
Before you start learning Java, you need to understand the basics:
In general, there are several steps in the sequence of learning programming:
To work in Java, you need to have the Java Runtime Environment installed on your computer, which is a virtual machine and contains a class library.
To develop programs, you need to install a special Java Development Kit. It already contains JRE and other necessary programs.
It is installed from the official Oracle website. The most important thing is to choose the right version for your operating system: Windows, Linux, MacOS.
The syntax of this language is uncomplicated because it consists of:
There are a large number of courses on Java available on various educational platforms that may appeal to the beginner:
To conclude, we want to highlight the key features of Java programming that make it most attractive to newcomers:
Programming is the future, so if you have the ability and desire, don’t hesitate to study.
