Better way to check string on null and empty java

/* You can use Apache Commons  */
StringUtils.isEmpty(str)
  
/* which checks for empty strings and handles null gracefully. */
  
/*   HINT   */  
/* the shorter and simler your code, the easier it is to test it */

How to check null and empty string in java

if(str != null && !str.isEmpty())
Be sure to use the parts of && in this order, because java will not proceed to evaluate the second part if the first part of && fails, thus ensuring you will not get a null pointer exception from str.isEmpty() if str is null.
