Java program: 1. Write a PaypalAccount class to include both balance and accountID as the instance variables. Make sure each instance of this account will have a unique accountID. In other words, different account object should have different accountID (hint: class variable). 2. Write a Bank class with main method. In the main method, ask the user to input how many accounts (say numOfAccount) to be generated in the bank (assuming less than 1000). Then create an array to hold these numOfAccount of Account objects. For eachAccount object, generate a random balance in the range of 0.0-1000.0. Assume that your campus ID is abc-de-fghi; search the array to see if there is an account with accountID as abc (the first three digits of your campus ID). If there is not an account with accountID as abc, then set the accountID of the last account in the array as abc; transfer all the balance of the first account to the account with accountID of abc. Set the balance of the account with accountID of abc to be efhi/100.0 (i.e your last 5 digits of your campus ID divided by 100.0); and print out the information of this account Find the average account balance of all the accounts in the array and print it out Find the account with the largest balance, print out its accountID and balance Find the account with the lowest balance, print out its accountID and balance. Ther is an example provided in the attachment. Campus Id: 141-88-2014

Java program:

1. Write a PaypalAccount class to include both balance and accountID as the instance variables. Make sure each instance of this account will have a unique accountID. In other words, different account object should have different accountID (hint: class variable).

2. Write a Bank class with main method. In the main method, ask the user to input how many accounts (say numOfAccount) to be generated in the bank (assuming less than 1000). Then create an array to hold these numOfAccount of Account objects. For eachAccount object, generate a random balance in the range of 0.0-1000.0.

Assume that your campus ID is abc-de-fghi; search the array to see if there is an account with accountID as

abc (the first three digits of your campus ID). If there is not an account with accountID as abc, then set the accountID of the last account in the array as abc; transfer all the balance of the first account to the account with accountID of abc.
Set the balance of the account with accountID of abc to be efhi/100.0 (i.e your last 5 digits of your campus ID divided by 100.0); and print out the information of this account
Find the average account balance of all the accounts in the array and print it out
Find the account with the largest balance, print out its accountID and balance
Find the account with the lowest balance, print out its accountID and balance.

Ther is an example provided in the attachment.

Campus Id: 141-88-2014

My Pather ID is 141-88-2014; my bank account ID is 141 and balance is: $820.14
The average balance is: $499.5
The account with the largest balance: accountID = 156, balance = 999.9
