Since arrays are objects in Java, we can find their length using the object property length. This is different from C/C++, where we find length using sizeof. A Java array variable can also be declared like other variables with [] after the data type. The variables in the array are ordered, and each has an index beginning with 0. Package java.util.function Description. Functional interfaces provide target types for lambda expressions and method references. Each functional interface has a single abstract method, called the functional method for that functional interface, to which the lambda expression's parameter and return types are matched or adapted.
