Question

Please help me with these array questions using java

3. A lottery requires that you select six different numbers from the integers
1 to 49. You have been given the duty to program a lottery program which
stores the winning numbers for a lotto 649 draw in the array
lotteryNumbers. You have bought two tickets, one set of numbers in the
array called firstSet and the other in an array called secondSet. Write the
function checkForJackpot() which returns true if ALL six numbers in the
array match the lottery numbers. The numbers are NOT guaranteed to be
in the same order.

1. Create a class with a method that accepts a charge account number as
its argument. The method should determine whether the number is valid by
comparing it to the following list of valid charge account numbers:
5658845 520125 7895122 8777541 8451277 1302850
8080152 4562555 5552012 5050552 7825877 1250255
1005231 6545231 3852085 7576651 7881200
These numbers should be stored in an array. Use a sequential search to
locate the number passed as an argument. If the number is in the array, the
methodshould return true, indicating the number is valid. If the number is
not in the array, the method should return false, indicating the number is
invalid.

Write a program that tests the class by asking the user to enter a charge
account number. The program should display a message indicating
whether the number is valid or invalid.
2. A teacher made a list of all of the marks in the class.
Print out the following things.
1. All of the marks in the class.
2. Every second mark in the class.
3. Every third mark in the class.
4. The marks backwards.
5. The marks vertically down the pages.
6. The marks with a % sign after them. Make sure that each entry has
a title before it.
