title: Ignore case for 'contains' for a string in Java
body: <p>Consider:</p>
  
  <pre><code>public static void main(String[] args) {
  
      String s = "AbcD";
  
      System.out.println(s.contains("ABCD"));
      System.out.println(s.contains("AbcD"));
  }
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>false
  true
  </code></pre>
  
  <p>I need the result to be true in both cases regardless of the case. Is it possible?</p>
