Conditionals in Java is a must know if you want to write code in Java that solves a problem. It is one of the most important building blocks in every programming language. In this article you will learn what are conditionals statements and how to use them. Commonly, in our life we take a decision […]

Expressions are an important tool for programmers. We can divide them into arithmetic and logic expressions. Let’s see what expressions are and how we can use them to solve problems. As stated here: “An arithmetic expression is an expression that results in a numeric value. There are two kinds of numeric values, integers (whole numbers),

Objects are a central concept in Object-Oriented Programming (OOP). In this article, you will learn what objects are in OOP and how to use them. From the previous lesson, we learned that “In Object-Oriented Programming, we use classes to represent concepts of the real world.”. In other words, a class is used to represent a

Java is one of the several programming languages one can use. In this article, you will find a very short introduction to Java, which is all you need to start writing computer programs. So, Java is a programming language, but: What is a programming language? Informally, a programming language is a way that we (programmers,

Applying algorithms is the goal when you want to use a programming language to solve problems. In the last unit of this course we studied how to create simple algorithms. This one, is about how to apply those algorithms using a programming language. If you missed the first unit, you can find it here. Notice

Class is the main concept in Object-Oriented Programming. If you really want to understand and use object-oriented programming, you must master the concept of Class. In this article I’ll answer the following questions: What is Object-Oriented Programming (OOP)? Which is the main concept in OOP? What are a data structure and an abstract data type (ADT)?

In this lesson you will learn an important topic: algorithms with repetitions (a.k.a. loops). You will see how to solve problems creating algorithms with repetitions. During the lesson you will see some examples. The approximate time to complete this lesson is 20 minutes. Transcription Welcome back. So far, we studied algorithms, conditionals relational and logical

This lesson explores the use of conditionals to construct algorithms. You will see some examples on how to use conditionals to solve certain type of problems. The approximate time to complete this lesson is 15 minutes. Transcription Welcome back. In this lesson we are going to keep studying algorithms. In this case we are going
