![]() In order to do this, a Java compiler runs a flow analysis to ensure that, for every assignment to a blank final variable, the variable is definitely unassigned before the assignment otherwise a compile-time error occurs. it must be unassigned when an assignment occurs. A blank final, by definition of "final", can only be assigned once. Previous to Java 1.1, a final variable was required to have an initializer. The blank final, which was introduced in Java 1.1, is a final variable whose declaration lacks an initializer. As doing this can confer security and efficiency benefits, many of the Java standard library classes are final, such as and. Final classes Ī final class cannot be subclassed. This applies also to arrays, because arrays are objects if a final 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. If a final variable holds a reference to an object, then the state of the object may be changed by operations on the object, but the variable will always refer to the same object (this property of final is called non-transitivity ). ![]() Once a final variable has been assigned, it always contains the same value. In the Java programming language, the final keyword is used in several contexts to define an entity that can only be assigned once.
