Hi all,
Below is some code from this lab. In the For Loop below the following
question is asked:
// * The equals(..) is a method of String class. Think about why you
// cannot use "names[i] == searchName" as comparison logic here.
Is the correct answer... "Becuase searchName is an instance of the
String class and to access it's value you must use the String class
method "equals"?
Thanks!
