Aim To write a program for demonstrating packages using Java. Theory A package is a group of related classes. A package is used to restrict access to a class and to create namespaces. If all reasonable class names are already used, then we can create a new package (new namespace) and reuse the class […]
Aim To write a program for demonstrating inheritance and method overriding. Theory Inheritance Inheritance is defined as: Deriving properties and behavior of one class to another class. The class from which things are derived is known as super class and the class in to which things are derived to is known as sub class. […]
Aim To write a program for demonstrating methods and method overloading. Theory One of the ways through which Java supports polymorphism is overloading. It can be defined as creating two or more methods in the same class sharing a common name but different number of parameters or different types of parameters. You should […]
Aim To write a program for demonstrating constructors. Theory A constructor is a special method which has the same name as class name and that is used to initialize the objects (fields of an object) of a class. A constructor has the following characteristics: Constructor has the same name as the class in which […]
Aim To write a program for demonstrating data types, variables, operators, arrays, and control structures in Java. Theory Data Types A data type specifies the type of value a variable can store or the type of an expression. Java is a strongly typed language means that you should specify the type of a variable […]
Aim To write a program for demonstrating the basic structure of a Java program. Theory A Java program is a collection of one or more classes, in which, one class contains the main method. Before looking at the structure of a Java program, let’s see the structure of a Java class. Structure of a […]
Introduction Debugging is a necessary skill for all programmers. Even the most experienced developers make mistakes or encounter unexpected behavior when writing code. Fortunately, Python provides a variety of tools and techniques for identifying and fixing bugs in your code. In this article, we’ll look at some of the most common Python debugging techniques. […]
In this article we will learn about the Python keywords. First we will see a list of Python Keywords followed by the description of each keyword. Following are keywords available in Python: Now, let’s look at the description of each keyword: False – False boolean value True – True boolean […]
In this article we will learn about creating and naming variables in Python programming language along with examples. What are Variables? Variables are just names of memory locations. Variables are used to store and retrieve values from memory. Type of the variable in Python is based on the value we assign to the variable. […]
In this article we will learn how to create and run a Python script. Actually the process is quite simple. Let’s see it. A Python script is a file containing multiple lines of Python code saved with .py extension. A Python script can be directly executed line by line without any need to compile […]
