compare two strings in java
<p>I created one Java program to compare two strings:</p>

<pre><code>String s1 = "Hello";
String s2 = "hello";

if (s1.equals(s2)) {
    System.out.println("hai");
} else {
    System.out.println("welcome");
}
</code></pre>

<p>It displays "welcome". I understand it is case sensitive. But My problem is that I want to compare two strings without case sensitivity I.e I expect the output to be "hai".</p>
