<p>Here goes the code to Sort array </p>

<pre><code>   String[] stringArray = { "Barbara", "James", "Mary", "John",
            "Patricia", "Robert", "Michael", "Linda" };
    Arrays.sort(stringArray, String::compareToIgnoreCase);
    for(String s:stringArray)
    System.out.print(s + " ");
</code></pre>
