Answers for "java check is empty"

java string is null or empty

public class Null {
 
	public static boolean isNullOrEmpty(String str) {
        if(str != null && !str.isEmpty())
            return false;
        return true;
    }
}

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 */
