Java is an Object-Oriented Programming language.Thus, Java code written on one machine can run on other machines. The platform-independent nature of Java makes it portable.Java is a platform-independent programming language.Master of Science in Computer Science from LJMU & IIITBĬaltech CTME Cybersecurity Certificate ProgramĮxecutive PG Program in Full Stack DevelopmentĪ Java tutorial for beginners is incomplete without listing the main features of Java. Thus, we say that Java is a platform-independent programming language.Įxplore our Popular Software Engineering Courses Although each operating system has a different JVM, their output after executing the bytecode is the same across all operating systems. The compiler takes the java program as input and returns Java bytecode as the output. The program compilation is done by the javac compiler included in the Java Development Kit (JDK). The Java Virtual Machine or JVM executes the bytecode generated by the compiler and translates it into machine language. JRE must be installed in the system if a user wants to run Java programs.Ĭheck out upGrad’s Full Stack Development Bootcamp (JS/MERN) 3. Java Runtime Environment is a part of JDK and contains JVM, class libraries, applets support, and browser plugins. JDK helps users code, compile, and run Java programs, and it can be used on macOS, Windows, Linux, and Solaris. It includes Java Runtime Environment (JRE), compilers, and various tools such as Java debugger, JavaDoc, etc. The Java Development Kit or JDK is a complete software development environment for making Java applications and applets. These components translate the source code (human-readable language) into machine language or executable code. Next, in this Java learning tutorial, we’ll look at some of the key components of the Java platform.
