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

You can always do:

int i, j;
for (i = j = 0; j < foo.length; ++j)
  if (!"a".equals(foo[j])) foo[i++] = foo[j];
foo = Arrays.copyOf(foo, i);
