Select the correct answerConsider the following Java class: public class MyClass {    private String name;    private int age;    public MyClass(String name, int age) {        this.name = name;        this.age = age;    }    // Overriding the toString() method    @Override    public String toString() {        return "MyClass{" +                "name='" + name + '\'' +                ", age=" + age +                '}';    }    public static void main(String[] args) {        MyClass obj = new MyClass("John", 25);         System.out.println(obj);    } }What is the purpose of overriding the toString() method in this class?A. To convert the object to a JSON representation.B. To provide a string representation of the object for easy debugging and logging.C. To make the object eligible for garbage collection.D. To create a new instance of the class.OptionsA and BOnly BOnly AB and C

Select the correct answerConsider the following Java code:public class Student {    private String name;    private int age;    public Student(String name, int age) {        this.name = name;        this.age = age;    }    // Override the equals() method    @Override    public boolean equals(Object obj) {        // TODO: Implement the equals() method    }    public static void main(String[] args) {        Student student1 = new Student("Alice", 20);        Student student2 = new Student("Bob", 22);        Student student3 = new Student("Alice", 20);        System.out.println(student1.equals(student2));         System.out.println(student1.equals(student3));    }}What should be implemented inside the equals() method to correctly compare two Student objects based on their name and age?A. return this.name.equals(obj.name) && this.age == obj.age;B. return this.name.equals(((Student) obj).name) && this.age == ((Student) obj).age;C. return super.equals(obj);D. return this == obj;OptionsCA and BOnly AD

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.
