Problem
I am needing to write my own
IsNullOrWhiteSpace check for Java but am wondering if this is the best method to do sopublic static boolean isStringNullOrWhiteSpace(String value) {
if (isStringNullOrEmpty(value)){
return true;
}
for (Character chars : value.toCharArray()){
if (!Character.isWhitespace(chars)) return false;
}
return true;
}Solution
I agree that the String should be left out of the name, as this is quite obvious in StringUtils. How about this short version?
public static boolean isNullOrWhiteSpace(String value) {
return value == null || value.trim().isEmpty();
