Conditionally add an item to an array in Java

Question

I'm trying to figure out how to add an item to an array based on the return value of a method.

Something like where in a method you can do return array.contains(value) and automatically return a boolean, but in a way where you can, instead of returning that value, add it to an array?

Is this possible in the same format, where you don't need a conditional statement?

Sorry for the noonish question, and thanks for the help!

If you don't want to return something, then why not just use a conditional statement? What do you mean? — pjpj

You could work with streams. e.g. to take all numbers from array1 that are bigger than 5 and put them into array2 you could write int[] array2 = Arrays.stream(array1).filter(n -> n > 5).toArray() — Tesseract

I think what you mean is this:

if(array.contains(value)){
    array2.add(value)
}
