The correct answer is: A. class
A class is a pattern for creating an object. It is a blueprint for creating objects. It defines the properties and methods that an object will have.
An attribute is a property of an object. It is a piece of data that describes the object.
A private attribute is an attribute that can only be accessed by the class in which it is defined.
A public attribute is an attribute that can be accessed by any class.
Here is an example of a class:
“`class Person {
String name;
int age;
void speak() {
System.out.println(“My name is ” + name + ” and I am ” + age + ” years old.”);
}
}
“`
In this example, the Person class has two attributes: name and age. It also has a method called speak(). The speak() method can be called on any object of type Person.
