Write Java programs with loops that compute:a. The sum of all even numbers between 2 and 100 (inclusive).
b. The sum of all squares between 1 and 100 (inclusive).
c. All powers of 2 from 20 up to 220.
d. The sum of all odd numbers between a and b (inclusive), where a and b are inputs.
e. The sum of all odd digits of an input. (For example, if the input is 32677, the sum would be .)

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
