Java eqivalent method of “splice(a,b,…)” in JavaScript method

Question

someArray.splice(a,b,...) method in JavaScript adds or removes items to/from array. What could be good and simple solution to implement such method in Java lang

Answer 1

Java arrays have a fixed length, so there's no such method.

You could imagine writing a utility function similar to splice in Java but it would return a different array. There's no point in having arrays in java if you resize them: it's not efficient and you can't share the instance.

The usual and clean solution is to use a List, which is a resizeable collection. ArrayList, the most commonly used List implementation is backed by an array but is efficient as the array isn't changed every time you resize the collection.
