Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

A coding interview, technical interview, programming interview or Microsoft interview is a technical problem-based job interview technique to assess applicants for a computer programming or software development position. Modern coding interview techniques were pioneered by Microsoft during the 1990s [1] and adopted by other large technology ...
This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language. Note that any referenced "value" refers to a 32-bit int as per the ...
OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). [2] It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License 2 with a linking exception , preventing components that linked to the Java Class ...
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.

Java and C++ use different means to divide code into multiple source files. Java uses a package system that dictates the file name and path for all program definitions. Its compiler imports the executable class files. C++ uses a header file source code inclusion system to share declarations between source files.
The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection algorithm used and any internal optimization of the Java virtual machine instructions (their translation into machine code) are not specified.
