The '''[[Syntax (programming languages)|syntax]] of [[Java (programming language)|Java]]''' is [[syntax|the set of rules]] defining how a [[Java (programming language)|Java]] program is written and interpreted.

The [[Syntax (programming languages)|syntax]] is mostly derived from [[C (programming language)|C]] and [[C++]]. Unlike in C++, in Java there are no global functions or variables, but there are data members which are also regarded as [[global variable]]s. All code belongs to [[class (computer science)|classes]] and all values are [[object (computer science)|objects]]. The only exception is the [[primitive types]], which are not represented by a class instance for performance reasons (though can be automatically converted to objects and vice versa via [[#Boxing and unboxing|autoboxing]]). Some features like [[operator overloading]] or [[unsigned integer]] types are omitted to simplify the language and to avoid possible programming mistakes.
