The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++ . Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables .
The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
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.

This is an example of a class invariant in the Java programming language with Java Modeling Language. The invariant must hold to be true after the constructor is finished and at the entry and exit of all public member functions. Public member functions should define precondition and postcondition to help ensure the class invariant.

[2] [3] Many of the most widely used programming languages (such as C++, Java, [4] and Python) are multi-paradigm and support object-oriented programming to a greater or lesser degree, typically in combination with imperative programming and declarative programming.
A program written in a low-level language can be made to run very quickly, with a small memory footprint. An equivalent program in a high-level language can be less efficient and use more memory. Low-level languages are simple, but considered difficult to use, due to numerous technical details that the programmer must remember.
