The Java runtime enables software developers to write program code in languages other than the Java programming language, which still runs on the Java virtual machine. Java is comprised of a runtime, core libraries, a compiler, and a programming language that are all described by a specification (Java virtual machine). The Java virtual machine and the Java core libraries are frequently linked to the Java platform.Java programs don’t directly touch the operating system; instead, they use the Java virtual machine as an abstraction. Java programs are very portable as a result. Java programs can run unaltered across all supported systems since they are standard-compliant and adhere to specified standards. All elements in Java are objects, except for rudimentary data types. Java is strongly-typed, which means that the types of the variables used must be predefined, and conversion to other objects is relatively stringent, requiring that the programmer perform the conversion in the majority of circumstances.

The conversion of Java source code into bytecode, which is independent of the target platform, is done. The Java Virtual Machine will understand these bytecode instructions (JVM). A feature known as the Hotspot-Compiler converts performance-critical bytecode instructions into native code instructions within the JVM. Java controls the allocation and release of memory while creating new objects. The memory is not directly accessible to the program. Objects without an active pointer are immediately deleted by the so-called garbage collector.
