Create a class called Employee having two attributes Id and Name Create a class?
Here's a simple implementation of a class called Employee in Python: class Employee: def __init__(self, id, name): self.id = id self.name = name This class has two attributes: id and name, initialized via the constructor. You can create instances of this class by passing the respective values for these attributes.
What is instantiable class with examples?
An instantiable class is a class that can be used to create instances or objects. In object-oriented programming, this means that you can use the class as a blueprint to create multiple objects with their own states and behaviors. For example, in Python, a class Car can be instantiable, allowing you to create different car objects like my_car = Car() and your_car = Car(). In contrast, an abstract class, which cannot be instantiated directly, serves as a template for other classes.
What are factory methods in java?
A factory class is any class which is used to create instances of other classes. The methods which create those classes are the factory methods. For example, the BorderFactory class has a variety of methods for creating instances of the different types of the Border classes. BorderFactory.createEmptyBorder(); BorderFactory.createEtchedBorder(); ...
Is python a case sensitive language?
Yes. For instance, you can write: x=2 X='a string' If you now print each of these variables you will find that they have retained the values that you assigned to them. Very often programmers create classes with uppercase names then use the lowercase version of the same name for instances of the class. This is possible because Python is case sensitive.
What is class 1 accuracy?
Class 1 accuracy refers to the proportion of correctly classified instances of a specific class (Class 1) in a classification task, relative to the total instances of that class. It is calculated by dividing the number of true positives (correctly predicted Class 1 instances) by the sum of true positives and false negatives (instances that belong to Class 1 but were misclassified). This metric is particularly useful in evaluating model performance in imbalanced datasets, where one class may dominate the others. High class 1 accuracy indicates that the model is effectively identifying instances of Class 1.

What is the purpose of a class attribute?
A class attribute is a variable that is shared by all instances of the class. It is used to store data that is common to all instances of the class, rather than specific to each instance. This can help avoid redundancy and ensure consistency across all instances.
What is need for static method?
Static methods are methods that can be invoked without creating an instance of the class that contains them. They are needed in cases where the programmer would not want to create multiple instances of a class to execute a method.
Is String are instances of the class string?
yes
What is factory methods?
Factory methods are merely a convention whereby static methods in a class return an instance of that class. The InetAddress class has no visible constructors. In InetAddress the 3 factory methods getLocalHost, getByName, getAllByName can be used to create instances of InetAddress.
What class or family does a python belong to?
Reptiles. I promise this is the correct answer.
What is class variable?
Class Variables or Instances variables are variables that are declared inside a class and are available for the whole class. They are available for all instances of that class and are not specific to any method. Ex: public class Test { private String name = "Rocky"; } Here name is a class variable.
Use of static variable in a class?
A static variable in a class is shared among all instances of that class, meaning it belongs to the class itself rather than to any specific object. This allows for data that is common to all instances to be stored in a single location, which can be useful for maintaining state or counting instances. Static variables can be accessed without creating an instance of the class, using the class name directly. However, they can lead to potential issues with data integrity if not managed properly, as changes from one instance affect all instances.
