![]() In fact, portability is a highlight of Java. Thus, like interpreted languages, it is possible to use a program without modifications if there exists a JVM implementation for the platform that will run the code. The intermediate representation can make Java programs portable for the platform that will run the code.Īs a result, one of Java's slogans is write once, run anywhere. Some JVM implementations may compile the bytecode when the program is being run, using a technique called Just-in-Time (JIT). Java is a compiled and interpreted language.Īt a first moment, the source code is compiled as an intermediate representation called bytecode.Īt a second moment, the bytecode is interpreted by a Java Virtual Machine (JVM). Unlike the previous languages, Java is, at its core, an object-oriented language (following the Object-Oriented Programming or OOP paradigm).ĭiscussions regarding OOP will have their own topics in the future.Īt this moment, an observable implication is that Java examples will be slightly different from those provided for other languages. In other words, the language provides abstractions, features and resources that allow programmers to focus on solving problems instead of worrying about how the hardware works. Like Python, Lua e JavaScript, Java is a high-level language. Nevertheless, the possibility of programming for mobile devices can serve as additional motivation to learn programming. Naturally, it should be noted that the applications must be simple to accommodate the needs of the beginners. If you do not want to use an IDE (or if the IDE requires manually installing the SDK), it is also easier to set up the JDK than a compiler for C and C++ (even on Windows).įurthermore, Java is the default language to create applications for the Android operating systems.Īlthough the complexity of programming for Android can be incompatible to beginners' skills, the transition is possible after acquiring some experience with Java. The IDEs BlueJ, DrJava and Greenfoot are three examples. Java as the First Programming Language Python and Lua lead my list of recommended programming languages for beginners, as previously commented in introduction about development environments the third option is JavaScript, due to the Internet.Īlthough the previous languages can be simpler for beginners, Java can also be a good option to start learning programming.Ī strong reason is that many universities with Computing courses (such as Computer Science, Computer Engineering and Information Systems) use the language either in introductory classes or as part of the curriculum.Ĭonsequently, there are multiple IDEs and tools to support learning the language. Therefore, if certain paragraphs seem familiar, it will not an impression, but déjà vu.Īs a matter of fact, this will also occur in new entries about development environments for other programming languages.Īfter all, the setup procedures are similar. Part of the contents of this page will be identical to the Python's page. If you are not experienced installing programs, Ninite can simplify the process. The topic can be particularly useful for Java because it is possible to install the JDK with Ninite. If you do now know how to install program, what is PATH or how to configure it, you can refer the topic regarding how to install programs.If you would rather use an IDE, the simplest option is choosing either BlueJ or Greenfoot, which includes a text editor, JDK and debugger among other features. ![]() The IDEs for the language often provide excellent support for programming. However, it can be preferable to use an IDE when programming in Java. ![]()
