Translate javascript code below into java

Question

I have javascript code like this:

var myArray = []; //integer
var anIndex = 1;
Array.prototype.delete = function (index) {
    var rest = this.slice(index + 1);
    this.length = index;
    return this.push.apply(this, rest);
};

and used like this:

myArray.delete(anIndex);

How to translate it into java code?

What's wrong with delete anArray[idx], or why not slice the array in de first place? Why augment the prototype (which is considered bad practice)? besides: questions asking to rewrite a snippet in another language are considered off-topic — Elias Van Ootegem

What java collection are you using?

If you are using java.util.List, it has a method .remove(int index) that does what you require -- removes an element from array.

If you are using java arrays (e.g. int[]), consider using collections such as java.util.ArrayList instead, they have the methods you need.
