Line 2:
In the [[Java (programming language)|Java programming language]], the <code>'''final'''</code> [[Keyword (computing)|keyword]] is used in several contexts to define an entity that can only be assigned once.
 
Once a <code>'''final'''</code> variable has been assigned, it always contains the same value. If a <code>'''final'''</code> variable holds a reference to an object, then the state of the object may be changed by operations on the object, but the variable always refer to the same object (this property of <code>'''final'''</code> is called ''non-transitivity''<ref>{{cite journal|last1=Coblenz|first1=Michael|last2=Sunshine|first2=Joshua|last3=Aldrich|first3=Jonathan|last4=Myers|first4=Brad|last5=Weber|first5=Sam|last6=Shull|first6=Forrest|title=Exploring Language Support for Immutability|journal=The 38th International Conference on Software Engineering|date=14{{ndash}}22 May 2016}}</ref>). This applies also to arrays, because arrays are objects; if a <code>'''final'''</code> variable holds a reference to an array, then the components of the array may be changed by operations on the array, but the variable will always refer to the same array.<ref>Java Language Specification #4.12.4</ref>
