How can I check if all values in an array have a certain value?

Question

In Java, given an array of values (say integers), is there a way to efficiently check to see if they all have a certain value?

For example, with an array of integers

Answer 1

Or, if using java 8, you can do something like:

if(Arrays.stream(numbers).allMatch(x -> x == 2)) {
    // do something
}

Basically, pretty much everything that you might want to do that deals with collections/arrays, can be very concisely done with the Streams.
