;<code>[[volatile variable|volatile]]</code>
:Used in field declarations to guarantee visibility of changes to variables across threads. Every read of a volatile variable will be read from main memory, and not from the [[CPU cache]], and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.<ref name="Java Volatile Keyword">{{cite web | title=Java Volatile Keyword | url=http://tutorials.jenkov.com/java-concurrency/volatile.html}}</ref> Methods, classes and interfaces thus cannot be declared ''volatile'', nor can local variables or parameters.
