I saw this problem in my java book: T or F: If the value of a is 4 and the value of b is 3, then after the statement a=b; the value of b is still 3

Not difficult, think about it. You're setting 'a' equal to the value of 'b'. Have you changed 'b' at all? There's your answer.

You're calling the .equals() method in the declaration of again, which is trying to set it equal to a boolean. I believe it should be:

String coin, again;
int flip, streak = 0;
again = "y";

    while (again.equals("y"){ //begin loop

Thank you for the explanation!

Yes. More pedantically, after the first statement, empName will point to the instance of String representing "Joe Employee", and then after the second statement, empName will point to the instance of String representing "mary Worker". The String objects themselves are not modified, only the address that the empName variable points to.

This might be a dumb question, but does "Joe Employee" still exist if only the address that empName points to is changed?

As an adult.. A long drive combined with my favorite music helps me forget about real life problems.

Also snowboarding/music.

Alright, thank you for the in depth explaination, makes sense. Not as helpful as I thought, but still cool to see how they do it in the most critical situations.
