2D array / recursion
explain every method

You are requested to write a Java program of a simpleMemory Management Unit.
The program should allow the following:
1. The user can create a process asking for memory. The programwill return a process ID if the requested memory can be allocated.It will also print the allocated Base and Limit.
2. The user can delete a process by specifying a process ID. Theprogram should do that and free any allocated memory for thedeleted process.
3. The user can, using a process ID, ask to convert between virtualaddresses and physical addresses.
4. The user can ask the program to print the memory map showingwhat memory is allocated and to which process.
Your program should be named mmu. When you start your program itprompts the user for the amount of memory to be managed inKB.
Your program should display a prompt for the user and should acceptthe following 4 commands:
1. cr AMOUNT_OF_REQUESTED_MEMORY
Description: Create a process and allocate the requested amount ofmemory (in KB) to it. The command should return the process ID andthe Base and Limit of the allocated memory. The command may returnan error message if there is not enough memory.
e.g. cr 1500
2. dl PROCESS_ID
Description: Delete the specified process and free the allocatedmemory. The command should return an error message if there is noprocess with the specified ID.
e.g. dl 6
3. cv PROCESS_ID VIRTUAL_ADDRESS
Description: Make a conversion for the specified process ID fromthe specified Virtual Address to the Physical Address. The commandshould return an error message if the process tries to access anaddress outside its address space.
e.g. cv 6 200
4.   pm
Description: Print the memory map. The command should print whichmemory locations are assigned.
e.g. pm

output

Enter amount of memory to be managed
