title: Android - Clean char array quickly and effectively
body: <p>Is it possible to clean a char array in Java (Android) quickly and effectively? Make an other loop on the treatment seem to be to much heavy to be an optimised solution, doesn't it ?</p>
  
  <p>It's strange but it is impossible to find such a solution in Java on the internet without having to subscribe to a pay site ..</p>
  
  <p>Thank's to your attention</p>
