Use Java To(With notes of Steps Please):

Write a program to create a class Customer. The properties of the customer are ssn, name, gender, account_No, balance. Include the following methods in the class. (20 marks)

a) changeName(String newName), which takes the new name and changes the name of the customer.

b) doTransaction(float amount), which takes the amount (which can be positive or negative) and changes the balance of the customer.

Solution

Customer.java

public class Customer {

   // Declaring instance variables
   private String ssn;
   private String name;
   private char gender;
   private int account_No;
   private float balance;

   // Parameterized constructor
   public Customer(String ssn, String name, char gender, int account_No,
           float balance) {
       super();
       this.ssn = ssn;
       this.name = name;
       this.gender = gender;
       this.account_No = account_No;
       this.balance = balance;
   }

   // This method is used to modify the name of the Account Holder
   void changeName(String newName) {
       this.name = newName;
   }

   /*
   * This method is used to perform the transactions like depositing the
   * amount or withdraw the amount
   */
   void doTransaction(float amount) {
       this.balance = balance + amount;

   }

   // toString method is used to display the contents of an object inside it
   @Override
   public String toString() {
       return \"SSN=\" + ssn + \", Name=\" + name + \", Gender=\" + gender
               + \", Account No=\" + account_No + \", Balance=\" + balance;
   }

}
