Java is an object-oriented, high-level programming language written in Java. It was originally developed in the mid-1990s by Oracle Corporation (now Oracle) parent company (Sun Microsystems). The JVM (Java Virtual Machine) is used to execute Java bytecode. The JVM is based on the “Write once, run anywhere” (WORA) philosophy, which allows Java programs to run on any machine or operating system that supports Java, without having to recompile them.
One unique aspect of Java is its bytecode format. When you compile a Java program, it is translated into bytecode, a highly optimized set of instructions designed to be executed by the JVM. This bytecode can then be run on any device or operating system with a compatible JVM, providing a level of portability and versatility not often seen in other programming languages.
Another unique feature of Java is its garbage collection mechanism. Java automatically manages memory allocation and deallocation through a process called garbage collection. This means that developers do not need to manually allocate and deallocate memory, reducing the likelihood of memory leaks and other memory-related errors.
