How do I remove objects from an array in Java?

Question

Given an array of n Objects, let\'s say it is an array of strings, and it has the following values:

foo[0] = \"a\";
foo[1]          


        

Answer 1

Something about the make a list of it then remove then back to an array strikes me as wrong. Haven't tested, but I think the following will perform better. Yes I'm probably unduly pre-optimizing.

boolean [] deleteItem = new boolean[arr.length];
int size=0;
for(int i=0;i
