Check if a specific string contains any lower/uppercase : <p>Is there a way to check if a <strong>specific</strong> string contains any lower/upper case ?</p>

<p>E.G :</p>

<pre><code>String myStr = "test";
if (myStr.contains("test") { // I would like this condition to 
                                check the spell of "test", weather it is
                                written like "Test" or "teSt" etc...
//Do stuff
}
</code></pre>

<p>With this syntax, it works only for the exact same string. How could I make my condition for anyform of "test", like : "Test", "tEst", "tesT" etc... ?</p>
