In functional programming, functions are first-class citizens, meaning that they can be passed around as values, stored in variables or data structures, and used as arguments or return values of other functions. Before Java 8, parallelization was complex. The emergence of the ExecutorService and the ForkJoin simplified a developer’s life a little bit, but it was still worth remembering how to create a specific executor, how to run it, and so on. Java 8 introduced a way of accomplishing parallelism in a functional style.

Size of multidimensional arrays: The total number of elements that can be stored in a multidimensional array can be calculated by multiplying the size of all the dimensions. For example: The array int [] [] x = new int [10] [20] can store a total of (10*20) = 200 elements. Similarly, array int [] [] [] x = new int [5] [10] [20] can store a ...

So in Java there will be classes and code will be written in classes so they are called methods instead of functions, as they will be associated with objects. But in C++ you can have some function that can be called by passing values explicitly. In simple terms you can say, a method is a function that is related to an object.In Java, Method Overloading allows different methods to have the same name, but different signatures where the signature can differ by the number of input parameters or type of input parameters, or a mixture of both.

As we’re starting to see, the double colon operator – introduced in Java 8 – will be very useful in some scenarios, and especially in conjunction with Streams. It’s also quite important to have a look at functional interfaces for a better understanding of what happens behind the scenes.
