C
public static void main(String[] args) {
String s =” “;
s.trim();
System.out.println(s.equals(“”)+” “+s.isEmpty());
}
false false
Answer C:
the str.trim() got ignored (i.e. has not been saved to any variable. So str remains as it is.
An empty space in a string (i.e. ” “) is actually filled with a blank character, meaning that this String is not empty.
