Would have greatly benefitted from being 15 minutes longer. Waaaaay too much was cut. The scene after Harry came out of the Pensieve should have been much longer. We should have seen at least a little bit of the Dursleys- they weren’t even mentioned. Lots of other stuff, too, but I won’t go into it the rest. Also, what was up with the performances by the other schools as they walked into the great hall at the beginning? Totally superfluous, totally not in the books. Wasted time that could have been better used. Same for the extended scene with the dragon. General opinion: Not as bad as I was afraid it would be, not as good as I was hoping it would be.

Java troubles part 2
FINISHED!
My God, that was hell.
In case anyone was wondering what the heck I was supposed to be doing with that, the question was:
“Often on a Web page, the user is asked to supply personal information, such as a telephone number. Your program should take an input from the keyboard representing a telephone number. We will consider that the input is a valid telephone number if it contains exactly 10 digits and any number of dash (-) and whitespace characters. Keep prompting the user for a telephone number until the user gives you a valid one. Once you have a valid telephone number, you should assume that the digits (only the digits, not the hyphen[s] nor the whitespace) in the telephone number may have been encrypted by shifting each number by a constant value. For instance, if the shift is 2, a 0 becomes a 2, a 1 becomes a 3, a 2 becomes a 4, …, an 8 becomes a 0, and a 9 becomes a 1. However, we know that the user is from New York, where the decrypted area code (after the shift is applied), represented by the first three digits of the input, is 212. Your program needs to decrypt the telephone number and output the decrypted telephone number with the format 212-xxx-xxxx, as well as the shift value of the encrpytion. If there was an error in the input and the area code cannot be decrpted to 212, you should output that information.

And it works! WOOHOO! That was a nightmare. eesh.
Anybody reading this know much about Java?
I’m working on a program for the Java programming class I’m taking. I’m having trouble getting it to work right. Anyone know anything about Java and think you can possibly help me?
So, a sample result of running the program is below:
Please enter the encrypted phone number: 4348885548
Exception in thread “main” java.lang.StringIndexOutOfBoundsException: String index out of range: 10
at java.lang.String.charAt(Unknown Source)
at PhoneNumberDecrypt.main(PhoneNumberDecrypt.java:137)
and down there is the code.
I’m stumped.
