Help with basic programing
I'm taking an AP course in high school Java and I have an assignment, in which I have no idea where to start. Unfortunatly my tutour is unavailable until after the due date. Can someone have a look at the 3 of them an offer any code please, I have no idea of what to do?
1)Write a complete Java program that will simulate a magic 8-ball?
The real magic 8-ball provides 20 different answers to yes/no
questions. Our 8-ball will include only eight different possible answers,
one of which will be chosen randomly for each question asked.
Some details:
Your program will do the following:
1. After outputting a brief welcome message, ask the user to enter
a question. Also, mention that the user can press 'q' or 'Q' to
quit.
2. If the question does not end in a question mark, echo the
original input, and then output "That is not a question".
3. If the question ends in a question mark, use Math.random() to
choose a random value between 1 and 8, and use this value to
select one of the below eight answers. Output both the original
question and the selected answer.
4. After the output message, prompt the user to input another
question or press 'q' or 'Q' to quit. After the user chooses to quit,
output a brief farewell message.
Signs point to yes.
It is decidedly so.
Outlook good.
Reply hazy, try again.
Cannot predict now.
My sources say no.
Very doubtful.
Don't count on it.
2)Write a complete Java program that will simulate Lotto 6-49.
For those of you who don't know the rules of Lotto 6-49, here's a brief
overview:
Tickets cost $2 each. For each ticket, customers pick 6 numbers
between (and including) 1 and 49. On Saturdays, the lotto organizers
pick 6 numbers and 1 bonus number.
Write a program that will simulate how much money a million dollars
worth of lottery tickets (that is, 500,000 tickets) would have won on
the draw of Saturday, October 8.
IMPORTANT NOTE: In this version of the simulation, you will randomly
generate a number, and then essentially put the number back into the
pool of possible numbers. In the actual Lotto 6-49, once a number is
drawn it cannot be drawn again. So, remember this simulation is not
accurate! Expect unusually lucky results from this version of the
program. And don't go and spend all of your money on lottery
tickets!
Overview:
The user will enter the 6 winning numbers, plus the bonus number.
The program will simulate the purchase of 500,000 randomly-
generated tickets, and output the winnings earned from these tickets.
Your program will do the following:
1. After outputting a brief welcome message, ask the user to pick
the 6 winning numbers. Also prompt the user to enter a bonus
number.
2. Then, use Math.random() to generate a random number
between 1 and 49. This number will represent one of the
numbers on a lottery ticket.
3. Compare this random ticket number to the winning numbers.
Keep track of any matches. Generate and compare numbers six
times.
4. Calculate how much money the lottery ticket made, using the
above table from Saturday, Oct. 8.
5. Now, repeat the above 4 steps half-a-million times to represent
a million dollars of lottery tickets! Remember to keep a running
total of the income.
6. Output the final winnings.
Thanks in advance to anyone who can help me, like I said before, I'm in the dark and really can't afford to loose the marks.

the correct way to get help in forums like this is to post:
1) the specific problem you have
2) the code you have tried
3) the 'output you expect'
4) the 'output you get'
5) any relevant error messages
posting the assignment makes it look like just another
"do my homework for me" plea - even though that may not be your intention.
Don't post a school assignment sheet on the forum.You shall fall a prey to angry monsters and be eaten by them.Post a result of your own effort and the description of the problem encounteredtherein.

did that wesson guy actually do his homework for him? i wish my homework would be that easy... they told him exactly what to do.. and that's AP...? my AP next semester will be 3D... im scared

AP stands for "Advanced Placement" which indicates that the course is intended to give the student enough of a background in computer science to complete the AP exam at the end of the year which, given a high enough score, is worth college credit.
Not that we have to worry about the OP receiving such credit should this prove to be an accurate example of his work ethic.

It should be ok, Wesson is free that day to take it for him :)
