Given the following set of classes, what would need to be fixed to make the program work?public class Customer { private String userName; private String password; public Customer(String userName, String password) { this.userName = userName; this.password = password; } public void setPassword(String password) { this.password = password; } public String getPassword() { return password; } public void setUserName(String userName) { this.userName = userName; } public String getUserName() { return userName; }} class CustomerTest { public static void main(String[] args) { Customer testAcct = new Customer("user","pass"); testAcct.setPassword("Java"); resetAcct(); } public static void resetAcct(Customer acct){ acct.setPassword(""); acct.setUserName(""); }}The instance testAcct is not in scope in the method resetAcct(). The instance testAcct needs to be declared in resetAcct()The testAcct should be returned as a return value from resetAcct().The testAcct should be declared at the class level to be accessed in the resetAcct() method.The testAcct should be passed into the resetAcct() method as a parameter.

Given the following set of classes, what needs to be fixed to make the program produce the output Name: Java?public class Customer { private String userName; private String password; public Customer(String userName, String password) { this.userName = userName; this.password = password; } public void setPassword(String password) { this.password = password; } public String getPassword() { return password; } public void setUserName(String userName) { this.userName = userName; } public String getUserName() { return userName; }}class CustomerTest { public static void main(String[] args) { Customer c1 = new Customer("user","pass"); c1.setUserName("Java"); outputName(); } public static void outputName(){ System.out.println("Name: " + c1.getUserName()); }} a.)The c1 should be returned as a return value from outputName().b.)The c1 should be passed into the outputName() method as a parameter.c.)The instance c1 is not in scope in the method outputName(). The instance c1 needs to be declared in outputName()d.)The instance c1 is not in scope in the method outputName(). The c1 should be globally in CustomerTest to be accessed in the outputName() method.

Given the following class, what sets of statements would have the end result of the myUser instance having the username as testuser and the password as testpassword?public class User { private String userName; private String password; public User(String userName, String password) { this.userName = userName; this.password = password; } public String getUserName() { return userName; } public String getPassword() { return password; } public void setUserName(String userName) { this.userName = userName; } public void setPassword(String password) { this.password = password; }}a.)User myUser = newUser("testpassword","testuser");b.)User myUser = newUser("username","password");myUser.setUserName("testuser");myUser.setPassword("testpassword");c.)User myUser = new User();myUser.setUserName("testuser");myUser.setPassword("testpassword");d.)User myUser = newUser("testuser","testpassword");myUser.setUserName("user");myUser.setPassword("pass");

Demonstrate ability to set and change the values of object properties.Given the following class, what sets of statements would have the end result of the myCustomer instance having the username as XC1001 and the password as testpass?public class Customer { private String customerCode; private String password; public Customer(String customerCode, String password) { this.customerCode = customerCode; this.password = password; } public String getCustomerCode() { return customerCode; } public String getPassword() { return password; } public void setCustomerCode(String customerCode) { this.customerCode = customerCode; } public void setPassword(String password) { this.password = password; }}a.)Customer myCustomer = newCustomer("testpass","XC1001");b.)Customer myCustomer = new Customer("username","password");myCustomer.setCustomerCode("XC1001");myCustomer.setPassword("testpass");c.)Customer myCustomer = newCustomer("XC1001","testpass");myCustomer.setCustomerCode("user");myCustomer.setPassword("pass");d.)Customer myCustomer = new Customer();myCustomer.setCustomerCode("XC1001");myCustomer.setPassword("testpass");

You have a class Student:public class Student{ public int studentId; public String studentName; public String studentGrade; public Student() { } public Student(int studentId, String studentName, String studentGrade){ this.studentId = studentId; this.studentName = studentName; this.studentGrade = studentGrade; }}You have a child class CollegeStudent:public class CollegeStudent extends Student {}Then you execute the following snippet of code:CollegeStudent myCollegeStudent = new CollegeStudent(1, "Alice", "3rd");What is the error in this snippet of code?Instruction: Choose the option that best answers the question. Answer ChoicesYou cannot specify multiple constructors for the parent class, though this is allowed in child classesYou cannot use the parameterized constructor in the base class to instantiate the CollegeStudent derived classYou need to have additional constructors in the base class to support the instantiation of the CollegeStudent derived classYou have to use the “object” keyword to create an object of a derived class
