Hi Lmit

What's the function of this method?

First, you forgot to import StringUtils.
Second, there is no isBlank() method in StringUtils.

Regards,
Pedro

Hi Pedro,

Thank For your reply

isBlank() method is there in stringUtils which checks whether the string is whitespace, empty ("") or null.

the function of the method (which i want is)
I want to check whether is string is null or not.

Thanks,
Lmit

Hi Lmit

Sorry for my delay to answer.

Last time I imported routines.system.StringUtils. I think what you need is to import org.apache.commons.lang.StringUtils which contains isBlank() method.

Pedro

You appear to have an error in isBlank.

public static boolean isBlank(String str) {
int strLen;
if (str == null || (strLen = str.length()) == 0) {
return true;
}
for (int i = 0; i < strLen; i++) {
if ((Character.isWhitespace(str.charAt(i)) == false)) {
return false;
}
}
return true;
}

According to your example in the code picture you want to return true or false.
