In this tutorial, we will learn about the method in Java, how to define a method which can take a parameter or not, and also in case of a return data type or not for that method. We will fully learn about it. Components of… Read More

In this tutorial, we will learn about the constructor of a class, how to create them, what is the difference between the default constructor and the constructor we define and finally what is constructor overloading? Definition of the constructor In Java, the constructor is a… Read More

All objects in Java are defined based on a basic object, java.lang.Object. This Object object will allow Java to handle all objects from the time they are created until they are no longer used. In this tutorial, we will learn more about what I just… Read More

Next to Part 1, let’s take a look at the remaining two scopes of variables in Java, and look at the case of variables with the same name but different in scope, how Java handle that. The variable is inside an object The variable is… Read More

In Java, any variable can have the following scopes: The variable is inside any method. As a parameter of any method. The variable is inside an object (including fields, attributes, and variables that are not static variables). The static variable of a class. In this… Read More

In mathematics, we have priority between plus, subtraction, multiplication and division, in parentheses, in Java, there are similar things in priority between operators if they are used in the same expression. This tutorial, let’s learn about the priority of the operators in Java. Java has… Read More

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
