The Java™ Programming Language is designed as a versatile, concurrent, and strongly typed object-oriented language that utilizes a class-based structure. Typically, it is translated into bytecode that adheres to the specifications laid out in the Java Virtual Machine Specification. In this language, developers write source code in standard text files that conclude with the .java suffix. These source files are subsequently transformed into .class files through the use of the javac compiler. Unlike native processor code, a .class file comprises bytecodes, which serve as the machine language understood by the Java Virtual Machine (Java VM). To execute an application, the java launcher tool creates an instance of the Java Virtual Machine, allowing the compiled bytecode to run seamlessly. This process exemplifies the efficiency and portability that Java offers across various computing environments.
