Line 5:

The syntax is mostly derived from [[C (programming language)|C]] and [[C++]]. Unlike C++, Java is almost exclusively an [[object-oriented language]]. There are no global functions or variables, all code belongs to [[class (computer science)|class]]es and all values are [[object (computer science)|object]]s. The only exception is the [[primitive type]]s, which are not represented by a class instance due to 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.

'''Java syntax''' is constantly improved in major [[JDK]] [[Java version history|releases]]. The lastlatest improvements to the language happened in Java SE 7, which introduced such language features as [[#try-with-resources statements|<code>try</code>-with-resources statements]] and [[#Literals|binary literals]].
