InefficientEmptyStringCheck
String.trim().length() is an inefficient way to check if a String is really empty, as it creates a new String object just to check its size. Consider creating a static function that loops through a string, checking Character.isWhitespace() on each character and returning false if a non-whitespace character is found.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.strings.InefficientEmptyStringCheckRule
Example(s):
public void bar(String string) {
if (string != null && string.trim().size() > 0) {
doSomething();
}
}
