title: Masking input for credit card number in java
body: <p>I want to masking my input form for credit card number like this:</p>
  
  <blockquote>
    <p>Input your credit card number : 411111******1111</p>
  </blockquote>
  
  <p>So like a password input, but only partially.</p>
  
  <p>I'm using icefaces for the framework. if I use <code>ace:maskedEntry</code> , then only change the format of the data, not the text that I have to input.</p>
  
  <p>Thanks in advance before and sorry for my bad english.</p>
