We, Dr. Shahriar Hossain and Dr. Monika Akbar, are currently running our Java Video Lecture Series for beginners. We are following a sequence that we use in teaching a standard programming language course at the University of Texas at El Paso. Subscribe to receive notifications of new videos and articles.

Printing a pyramid pattern of stars in Java

Printing the pyramid pattern of stars in Java: Video Lecture 15

Printing the pyramid pattern of stars is a common practice in learning any programming language. In this post, we will learn how to print the pyramid pattern of stars in Java. The program output for a pyramid of ten lines of stars is provided below. Video lecture explaining how to print a pyramid of stars […]

Java do-while loop

Java do-while Loop: Video Lecture 14

Java do-while loop is one of the three looping techniques available with the language. The other two loops are: for loop and while loop. do-while is a little bit different than for or while loops. In the “for” or “while” loop, generally, a condition is checked in the beginning to realize whether the execution should […]

While loops in Java: Coding examples and comparison with for loops

While loops in Java: Video Lecture 13

Java has three types of loops: (1) for loop, (2) while loop, and (3) do-while loop. This post focuses on while loops in Java. In the video-lecture associated with this post, we compare side-by-side for loops and while loops. While loops in Java The while loop in Java has the following structure. The variable condition […]

Connected nested loops in Java

Connected nested loops in Java: Video Lecture 12

As stated in the previous video lecture, nested loops refer to the repetition of another repeated task. The nested loops we discussed in the last lecture were not dependent on each other in determining how many times a loop should iterate. In the exercise of this lecture, we demonstrate how we can ensure that the […]

Nested loops in Java

Nested loops in Java: Video Lecture 11

Nested looping refers to a loop inside another loop. Many applications require to loop over a repeated task. Nested looping is a solution to aid such repetitive tasks. As an example, consider printing ten lines on the terminal, where each line contains twenty asterisks, as shown below.

Java for-loop with if else. The post contains a video lecture explaining how to use if-else inside a for-loop.

An exercise on for-loops and if-else: Video Lecture 10

In the previous video lecture, we learned how to repeat a segment of code using a for-loop. The segment we used for repetition was small. In the following video lecture, we incorporate an if-else structure inside the scope of a for-loop. We use a simple problem to develop this practice scenario. The Problem used in […]

An introduction to Java for loop

An introduction to Java for loop: Video Lecture 9

Repetition of segments of codes is an essential part of programming. Repeating the execution of a code segment, a programmer can reduce the size of the code as well as solve problems that require iterations of similar computations for an arbitrary number of times. Java provides three syntaxes for repetition: for loop, while loop, and […]

Tracing a program with if-else if-else statements

An exercise, its solution, and tracing: if-else if-else in Java: Video Lecture 8

In the previous video-lecture, we described how if-else if-else statements work. We provided an exercise with the video-lecture. In the video with this article, we provide a solution to the exercise. Tracing a program with if-else if-else statements In the following video, we introduce a technique called tracing that we did not cover before. Tracing […]

if-else if-else statements in Java

if-else if-else statements in Java: Video Lecture 7

The article explains if-else if-else control statements in Java. It provides a video and relevant exercises.

Boolean variables and relational operators in Java

Boolean Variables and Relational Operators in Java: Video Lecture 6

A boolean variable is capable of holding either “true” or “false.” A computer program may use one bit only to store the status “true” or “false.” You might already know that the smallest memory unit of the computer is a “bit.” Therefore, a boolean variable uses as little memory as possible to store the information […]

Arithmetic Operations in Java Programming Language.

How to Use Arithmetic Operators in Java: Video Lecture 5

The article describes the arithmetic operators in Java programming language. It provides a video lecture, which uses simple programming examples to explain the concepts.

User Input in Java for Different Types of Variables

More on Data Types and User Input in Java: Video Lecture 4

The article covers user input in Java for different data types. It uses a simple example and great details for beginners. We also provide a YouTube video in this article that describes the fine details of how to write the program.

Getting user input in Java can be intimidating for beginners. With practice, it can become easy.

Getting User Input and Making a Calculator Using Java: Video Lecture 3

I am writing this article in support of the video we made on the topic — Getting User Input in Java. The video helps new learners by providing explanations on how to develop a simple calculator program. The user of the program types on the keyboard to enter two numbers. The program captures the two […]

A video tutorial on Variables in Java.

An Introduction to Variables in Java: Video Lecture 2

I am writing this article today in support of the video I made on Variables in Java. The video describes a little bit of theory and then demonstrates how you can use multiple variables in your program. I used simple applications — addition and subtraction of two numbers — to describe how to use variables […]

How to write your first Java program

How to Write Your First Program Using Java: Video Lecture 1

Writing the first program using Java can be intimidating, especially if someone is learning a programming language for the first time. Please do not be afraid or discouraged. If you saw someone write programs in the speed of light — especially in movies when there are only ten seconds left to a terrible happening, which […]
