A digitаl pаyment system keeps trаck оf transactiоns made by custоmers at a store’s point of sale (for example, the cashier). Each transaction is either a purchase, which increases the amount in the store’s account balance, or a refund, which decreases the amount in the store’s account balance. Information about each transaction is stored using the following Transaction class. A Transaction object stores a unique identifier for the transaction (an id), a purchase indicator, and a value in pennies. A partial declaration for the Transaction class is shown below. public class Transaction { /** Returns a unique identifier for this transaction */ public String getId() { /* implementation not shown */ } /** Returns true if the transaction is a purchase, false if it is a refund */ public boolean isPurchase() { /* implementation not shown */ } /** Returns the amount of this transaction, represented as a positive number of whole pennies */ public int getPennies() { /* implementation not shown */ } // There may be instance variables, constructors, and methods not shown. } Batches of transactions, sorted in ascending id order, are processed using a Register class. The declaration of the Register class is shown below. public class Register { // Precondition: payments is sorted in ascending id order private Transaction[] payments; /** Calculates the net effect of some transactions on the store's account balance, as described in part (a). Precondition: ids is not null */ public int calculateDelta(String[] ids) { /* to be implemented in part (a) */ } /** Changes payments to include a batch of new transactions, as described in part (b). Precondition: entries is not null, is sorted in ascending id order, and all id values are either before or after those in payments */ public void addBatch(Transaction[] entries) { /* to be implemented in part (b) */ } // There may be instance variables, constructors, and methods not shown. } B. Write the Register method addBatch, designed to add a new batch of transactions to the beginning or the end of the existing set of transactions stored in the payments instance variable. The addBatch method replaces the payments instance variable with a new array that includes all the original Transaction elements already in payments, plus all the new elements contained in the entries parameter The existing payments and the new entries are already both sorted in ascending order, and the new entries must be added either to the beginning or end of payments depending on whether their id values come before or after the existing values. The following example illustrates the results of two sequential calls to addBatch. The payments instance variable before the first method call. Recall that each object stores an id, a purchase indicator, and a value in pennies. "C1" "C2" "C3" true true false 100 300 250 A first call to addBatch includes the following array of transactions. "A1" "A2" false true 950 753 The payments instance variable after the first method call. "A1" "A2" "C1" "C2" "C3" false true true true false 950 753 100 300 250 A second call to addBatch includes the following array of transactions. "C4" "C5" "C6" true false true 1195 451 30 The payments instance variable after the second method call. "A1" "A2" "C1" "C2" "C3" "C4" "C5" "C6" false true true true false true false true 950 753 100 300 250 1195 451 30 Complete the addBatch method. /** Changes payments to include a batch of new transactions, as described in part (b). Precondition: entries is not null, is sorted in ascending id order, and all id values are either before or after those in payments */ public void addBatch(Transaction[] entries)
