Checking for Null or Empty in Java.
We can check whether a particular String is empty or not, using isBlank() method of the StringUtils class. This method accepts an integer as a parameter and returns true if the given string is empty, or false if it is not.
Example
import org.apache.commons.lang3.StringUtils;
public class Sample {
public static void main(String args[]) {
String str = "";
Boolean bool = StringUtils.isBlank(str);
System.out.println(bool);
}
}
Output
true
