copied!<p>[If you want some ready-to-use code, please scroll to my "Edit3" (after the cut). The rest is here for posterity.]</p> <p>To flesh out <a href="https://stackoverflow.com/a/112507/13">Dustman's idea</a>:</p> <pre><code>List<String> list = new ArrayList<String>(Arrays.asList(array)); list.removeAll(Arrays.asList("a")); array = list.toArray(array); </code></pre> <p>Edit: I'm now using <code>Arrays.asList</code> instead of <code>Collections.singleton</code>: singleton is limited to one entry, whereas the <code>asList</code> approach allows you to add other strings to filter out later: <code>Arrays.asList("a", "b", "c")</code>.</p> <p>Edit2: The above approach retains the same array (so the array is still the same length); the element after the last is set to null. If you want a <em>new</em> array sized exactly as required, use this instead:</p> <pre><code>array = list.toArray(new String[0]); </code></pre> <hr> <p>Edit3: If you use this code on a frequent basis in the same class, you may wish to consider adding this to your class:</p> <pre><code>private static final String[] EMPTY_STRING_ARRAY = new String[0]; </code></pre> <p>Then the function becomes:</p> <pre><code>List<String> list = new ArrayList<>(); Collections.addAll(list, array); list.removeAll(Arrays.asList("a")); array = list.toArray(EMPTY_STRING_ARRAY); </code></pre> <p>This will then stop littering your heap with useless empty string arrays that would otherwise be <code>new</code>ed each time your function is called.</p> <p>cynicalman's suggestion (see comments) will also help with the heap littering, and for fairness I should mention it:</p> <pre><code>array = list.toArray(new String[list.size()]); </code></pre> <p>I prefer my approach, because it may be easier to get the explicit size wrong (e.g., calling <code>size()</code> on the wrong list).</p>
