Program Plan Intro

Programmable Logic Controller (PLC):

  • Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
  • PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
  • The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
  • When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
  • The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language.

Central Processing Unit (CPU):

  • CPU is known to be the central part or component of a computer system.
  • CPU is also known as processor.
  • The process refers to an electronic circuit within a computer.
  • It carries out the program instructions for performing basic arithmetic, logic, controlling, and I/O operations.

Memory:

  • Memory refers to a computer part which holds data as well as instructions for processing.
  • It is also known as primary storage, primary memory, main memory, Random Access Memory (RAM), and internal storage.
  • Almost all types of memory stores the data when the computer is turned on and destroys the data when the machine is turned off.

Add a method called transfer () to the BankAccount class, that takes in an amount and destinationAccount as input and transfer the funds from current account to destination account. This method should return the balance of the current account after the transfer, also should check for the sufficient balance in current account before proceeding the transfer and if there is insufficient balance return an error message "Insufficient balance". Modify the BankAccount Test class, so that it calls the transfer () method and prints the balance after transfer. Make sure that the transfer() method updates the balance of both the current account and the destination account.
• Create a public method called deposit() that takes in an amount of type double as input and adds the amount to the current balance. This method should also return the updated balance. • Create another public method called withdraw() that takes in an amount of type double as input, checks if the withdrawal amount is less than the current balance, and if so, subtracts the amount from the balance. If the withdrawal amount is greater than the current balance, the method should return an error message "Insufficient balance". • Create a public method getAccountInfo() that returns the account information in the format "Account Number: xxxxx, Account Holder: John Doe, Account Type: SAVINGS/CHECKING, Balance: $xxxX.XX". • Finally, create a constructor method that takes in the account number, account holder name, initial balance and account type as input and initializes the corresponding instance variables. In the BankAccount class, make sure to use the private access modifier for the instance…
Create a BankAccount Test class that contains a main() method that instantiates an object of type BankAccount, with account number of 12345, account holder name of "John Doe", initial balance of $1000 and account type as SAVINGS . Then use the deposit() and withdraw() methods of the object to deposit $500 and withdraw $300. Finally, use the getAccountInfo() method to print the current account information. Use the getAccountInfo() method to verify that the deposit and withdrawal actions are performed correctly and that the account information is updated accordingly.
