In Java, we have two types of variables, the primitive variable and the object reference variable. The primitive we learned in the previous tutorials, in this tutorial I will be with you to learn about the object reference variable and its difference with the primitive… Read More

In our previous tutorial, we looked at five of the eight primitive data types in Java. Now let’s look at the 3 remaining primitive data types. float The float is a 32-bit data type that has a very large value. I do not list here… Read More

Primitive data types are the simplest types in every programming language in general and Java in particular. In Java, we have eight primitive data types: char byte short int long float double boolean Variables defined with primitive data types are called primitive variables. In this… Read More

The access modifier in Java defines the access rights of class and variables, methods of that class from outside the class and package. The non-access modifier in Java changes the properties of the class and the variables and methods of that class. For example, abstract… Read More

The access modifier in Java defines access to variables, methods of this class from other classes in the same package or in two different packages. There are four types of access modifiers in Java: public, protected, default, and private. Overview of each access modifier has… Read More

Talking about import command in Java, we may ask the following questions: What does the import command in Java do? The import command in Java makes us possible to use the name of other classes in our class without having to explicitly declare the name… Read More

In this tutorial, let’s learn how to define, the directory structure corresponding to the package in Java. Package in Java is used to group classes or interfaces that share some common points. We can define multiple packages in our project according to purpose. Package definition… Read More

To create an application that can be run in Java, the first requirement is that we have to create a class that contains the main() method with an array of String parameters. For example: The main() method must satisfy the following conditions: This method must… Read More
