Logical operators are used to test the validity of one or more expressions. The return value of these expressions is a boolean value, true or false. In Java, we have the following logical operators: AND (&&) OR (||) NOT (!) AND operator The AND operator… Read More

Relational operators in Java are used to test whether a condition is satisfied. They consist of the following six operators: > >= < <= == != >, >=, <, <= operators We use the operators >, >=, <, <= to check that this primitive value… Read More

In Java, we have seven mathematical operators including: +: plus –: subtraction *: multiplication /: division %: modular division ++: double plus —: double subtraction It is easy for plus, subtraction, multiplication, division, and modular division, isn’t it? So, in this tutorial, I will focus… Read More

In Java, we have the following assignment operators: = += -= *= /= – The assignment operator “=” is used most often, which is used to initialize the variable and assign a new value to it. Example: You cannot use this assignment operator to assign… Read More

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
