➤Java is a general-purpose, object-oriented programming language, a computing platform for app development that is designed to have lesser implementation dependencies.
➤Java comes with a bundle of features and is undoubtedly one of the fastest, and secured programming languages, used for developing applications in laptops, data centers, game consoles, scientific supercomputers, and so much more.
➤Our Java tutorial will help you understand and learn various concepts of this language like ways to create arrays, uses of array objects, regex, closure, and a lot more. So start learning now, and become a pro at Java!
Here are the topics covered in the Java Tutorial:
Java is an object-oriented and high-level programming language designed to work with a distributive environment and empower developers to implement write once, run anywhere (WORA) functionality. Written with C and some libraries of C++, Java comes with three editions as Java Standard, Java Enterprise, and Java Micro Edition - and this Java tutorial will help you understand all of it.
Arrays are a part of several programming languages. Java arrays represent dynamic allocation, homogeneous elements and have a contiguous location within a group. In this Java tutorial, you will also learn to define an array in Java along with the advantages and disadvantages of Java. There are three types of arrays - one-dimensional, two-dimensional, and multi-dimensional.
Java installation needs some specific hardware and software requirements in a system. The latest Windows versions above Vista (2006) are compatible with Java with a minimum of 128 MB RAM, a minimum of 124 MB disk space, and a running web browser as the main prerequisites. Multiple versions of the Java Development Kit (JDK), which are essential to run Java applications, are also available. JDK provides tools for interpreting predefined functions for Jar files, document generators, etc., to build robust applications. You will also get to learn the step-by-step process of setting up the environment for running Java in Windows in this Java tutorial.
Java programming functions seamlessly for developing either classes or objects in applications. In this lesson of the Java tutorial, you will learn about the concepts of classes and objects of Java. You will also learn about the definition of Java Classes, access modifiers, types, rules, and how to create them in a running Java environment.
Java is one of the essential requirements for starting with Eclipse IDE. In this Java tutorial, you will learn the process of installing Java by setting JAVA_HOME and JAVA_PATH. Eclipse IDE is available in multiple versions. You can download Eclipse from its official site and learn about building feature-rich applications in Java. And this lesson of the Java tutorial will help you understand how to run your first program.
Java Strings imply the character data type objects or arrays that store information and can be modified using a specific string class. In this lesson of the Java tutorial, You will also learn to create Java Strings using the String literals and new keyword methods. You also explore the practical use, examples, and different properties for effectively using Java Strings.
Encapsulation in Java defines the procedures for storing data methods and data members within a class together. Several reasons for implementing Encapsulation in Java include better control, enhanced security, improved flexibility, and in-built support for Getter & Setter. Get to know the procedure for Data Hiding in Java using four access specifiers as default, protected, public, and private. In this Java tutorial, learn the benefits of Encapsulation and its main difference from the concepts of Data Hiding.
Abstract Class in Java plays a crucial role in keeping the code structures hidden from the real-time users and offering only minimum information. In this Java tutorial, you will learn about the features, rules to declare, procedures, and syntax for implementing an Abstract Class.
Polymorphism defines the ability of an object to operate from multiple perspectives. Polymorphism in Java has two fundamentals with Compile-Time Polymorphism and Run-Time Polymorphism. The main characteristics of Polymorphism include a method to function diversely in diverse situations, behavior based on data, implicit type conversion, and empowering the same name for the method or member within a class. You will also learn the difference, advantages, and disadvantages between types of Polymorphism in this java tutorial.
JDBC (Java Database Connection) adds data processing capabilities to the system by connecting the standard database and Java application. JDBC has four basic needs for the database - connectivity with API, performing SQL queries, running DDL/ DML commands, and modifying data records in specific storage units. You will learn about JDBC architecture, its five segments as JDBC Application, JDBC API, JDBC Manager, JDBC Drivers, and Data Storage Units, and more in this java tutorial.
Inheritance is one of the essential, powerful features of Java. It empowers developers to inherit properties and data members from one class to another. Learn more about inheritance with base and subclass and their implementation in this java tutorial. Code reusability and run-time Polymorphism are the two main reasons that we need inheritance. Access modifiers control the accessibility of parent class in four ways as default, public, protected, and private.
The OOPs concept has revolutionized the Java programming language with its robust and powerful features. All the basic concepts of class, static, keyword, object, constructor, method, OOPs, Abstraction, Encapsulation, Inheritance, Polymorphism, Access modifiers, and Method calling will help you grasp the Java fundamentals.
This Java tutorial uses a practical approach and examples to help you learn this fundamental programming language effectively. Start learning the Java tutorial now and make a mark in the field of programming today!
