Strings – objects that contain a “string” of text.A framework, which defines the structure, the boundary of an object, its state. Persistent true, false, null, which perform their functions when included in the code.These are words that perform certain actions when used in code (if, else, for, float). The syntax of this language is uncomplicated because it consists of: The most important thing is to choose the right version for your operating system: Windows, Linux, MacOS. It is installed from the official Oracle website. It already contains JRE and other necessary programs. To develop programs, you need to install a special Java Development Kit. 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. mastering frequently used apis (junit, jdbc, jsp).acquaintance with popular libraries and frameworks.installing the jre (eclipse, netbeans, intellij idea, etc.).installing the java development kit software from the oracle website.In general, there are several steps in the sequence of learning programming: tools for deploying/running applications īefore you start learning Java, you need to understand the basics:.To master the language, you also need to understand: Substitute classes are needed to convert the basic data types, e.g. Other libraries need to be included by themselves using the import operator. Built-in classes are classes for solving system tasks and security system functioning, as well as class libraries for exception handling. To simplify the work of programmers, class libraries have been created, which are needed to implement the most common tasks.īuilt-in classes are classes that are plugged in automatically (e.g., java. Moreover, the recommended ratio of theory to practice is 20% to 80% per day. Without the practical day-to-day application of knowledge, your learning might take a long time. Secondly, at least roughly specify in what time frame and what topics you want to learn.Īnother point: to successfully master this programming language, just like any other, it is important to maintain a balance between theory and practice. Firstly, you need to understand how many hours a day you will devote to learning. You need to understand why you need the knowledge and what you want to do with it.Īnother important step is to make a timetable. It is advisable to start any learning process by setting clear goals. Its features are, for instance, case-sensitive. Java’s syntax is similar to other C-like languages. It automatically clears the memory and deletes objects that are no longer in use. The language uses the garbage collector mechanism, which performs the memory management function. This function is performed by a virtual machine, JVM, which is part of the Java Runtime Environment and is platform-independent. This is possible due to the compilation of the Java code into byte-code. Java is an object-oriented programming language with strict typing.Īpplications written in this language are easy to run from any platform, as long as JRE – Java Runtime Environment – is installed on the platform. learning the theoretical framework from scratch is realistic in 6 months (provided that you take the learning process seriously).īrief description of the programming language.
