Preventing CRLF injection

This code will encode your data if a user tries to attack your application through CRLF injection

String s=Arrays.toString(object);
if(s.contains("/") || s.contains(">")||s.contains("<")||s.contains("?") ||s.contains("&") ||s.contains(""))
{
 String validobject=URLEncoder.encode(s);
 System.out.println("the encoded data is"+validobject);
}
else
{
 System.out.println("the non-encoded data is"+object);
}
