Simulate first fit memory allocation algorithm we keep it simple. the number of memory partition (blocks) and size of processes are in units. the unit can be any size, say, 16 kbytes or 64 kbytes. a. in this part of the program, you will: • prompt the user to enter the number of blocks (3 to 5) • prompt the user to enter the number of processes (3 to 5) • you may prompt the user to enter block sizes and process sizes. you may also initialize them within the program. • implement the first fit algorithm. note that each process is checked against starting from the first block and gets allocated to the first block that fits it. • when the process gets allocated, output the information on where it is placed and the remaining block size. •

The width of a piece of rectangular land is 5m shorter rhan 1/3 of its length .find the width of the land if the length is 60m,150m.

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.
