JAVA for. Beginners. 2 nd. Edition. An introductory course for Advanced IT like to learn the Java programming language. . Character Escape Codes. complete source code for all examples in this tutorial series, plus exercises and . But, programs given to end users should almost never use command-line. Java programming language, originated in Sun Microsystems and released back in , Along the course, there will be a lot of code snippets to look at.
In addition, you can use Eclipse to organize source code files into projects, compile and test those projects, and store project files in any number of source repositories.
If you download one of the Eclipse bundles, it will come with the JDK already. Agree to the license terms for the version you want to download. Choose the download that matches your operating system and chip architecture. Windows Save the file to your hard drive when prompted. When the download is complete, run the install program. OS X When the download is complete, double-click it to mount it.
Run the install program. You do not get to choose where the JDK is installed. You now have a Java environment on your computer. Install Eclipse Browse to the Eclipse packages downloads page. Under Download Links on the right side, choose your platform the site might already have sniffed out your OS type. Click the mirror you want to download from; then, save the file to your hard drive. When the download finishes, open the file and run the installation program, accepting the defaults.
To set up your Eclipse development environment: Launch Eclipse from your local hard disk. When asked which workspace you want to open, choose the default. Close the Welcome to Eclipse window.
Java Tutorial For Beginners – Java Programming Made Easy!
The welcome window is displayed each time you enter a new workspace. Figure 1 shows this selection highlighted in the Eclipse setup window for the JRE. Figure 1. Eclipse is now set up and ready for you to create projects, and compile and run Java code. The next section familiarizes you with Eclipse. This section is a brief hands-on introduction to using Eclipse for Java development. The Eclipse development environment The Eclipse development environment has four main components: Workspace Perspectives Views The primary unit of organization in Eclipse is the workspace.
A workspace contains all of your projects.
A perspective is a way of looking at each project hence the name , and within a perspective are one or more views. Figure 2 shows the Java perspective, which is the default perspective for Eclipse. You see this perspective when you start Eclipse.
Figure 2. Eclipse Java perspective The Java perspective contains the tools that you need to begin writing Java applications.
Each tabbed window shown in Figure 2 is a view for the Java perspective. Package Explorer and Outline are two particularly useful views. The Eclipse environment is highly configurable. Each view is dockable, so you can move it around in the Java perspective and place it where you want it. For now, though, stick with the default perspective and view setup. Figure 3. New Java Project wizard Enter Tutorial as the project name and use the workspace location that you opened when you opened Eclipse.
Click Finish to accept the project setup and create the project. You have now created a new Eclipse Java project and source folder. Your development environment is ready for action. Object-oriented programming concepts and principles The Java language is mostly object oriented.
This section is an introduction to OOP language concepts, using structured programming as a point of contrast. What is an object? Object-oriented languages follow a different programming pattern from structured programming languages like C and COBOL. The structured-programming paradigm is highly data oriented: You have data structures, and then program instructions act on that data.
Object-oriented languages such as the Java language combine data and program instructions into objects. Cons: some topics, like generics, are covered less diligent than others. Like many others, it starts with an introduction to OOP. It is also a rather good reference book. Each chapter has the vocabulary and exercise sections to consolidate theory and master the skill of programming thinking.
It is more suitable for beginners than readers with even a small experience in coding. For starters, it is simple and kind of fun to read. Pros: a source for adjusting your way of coding, practice, basic concepts explained clearly.
Cons: cannot be considered as the complete reference for core Java; the same level of complexity in all exercises. Cheers to that! Effective Java is written by Joshua Bloch This is not a book for a complete beginner but is must-read research for every Java developer.
If you want to understand the inner processes and get a clue of how and why they are arranged this way, this book serves the purposes well. It will teach you how to write the code and how to do it well. Pros: easy to read, covers best practices in programming, useful advice for improving your coding. Cons: requires an understanding of core concepts and at least a small experience in coding.
It covers the Java 8 APIs, and clearly explains the basic concepts and beyond that. Pros: the real world examples, clear and detailed explanations, a good reference for the latest Java APIs. Cons: requires a basic knowledge of Java programming. Java 8 in Action If you need a Java 8 book with full coverage of its features, this one is for you.
It will be easier for you to understand the material with some background in Java. Just be sure not to mix them up : All in all, this is a book with an obvious focus on practice, so you can use it as an additional source for the enhanced studying.
Pros: focused on practice, shows the difference between the right and the wrong code. Cons: requires supplementary sources for a deeper understanding of Java basics. Thinking in Java by Bruce Eckel This book offers you a rather refreshing approach to explaining Java fundamentals.
It has a focus on Java language design and behavior, and includes many detailed explanations. You will get the understanding of how each topic fits in with OOP. The basic subjects are fully covered on the first pages of the book. The larger part can help you to cover the new ground.
It is one of those books, which you will return to even after years of studying and coding. Although some of the examples are a bit outdated, this book is still a profound source for learners, because it actually teaches you to think like a Java programmer and encourages you to code.
Pros: a thorough source, plenty of code samples and exercises, excellent explanation of OOP concepts in Java. Cons: might be too complicated for a beginner.
Most Beginner Friendly Tutorials for Programmers

New Java Project wizard Enter Tutorial as the project name and use the workspace location that you opened when you opened Eclipse. This is similar to a hello world Java program. In char, you can store any alphabetical character as well as a special character.
Each chapter is devoted to a certain subject, starting from introduction to the language and Java programming environment and moving to data structures, objects and classes and so on.
For example: you want to eat pizza, but then where can you get that pizza in best price. Eclipse handles basic tasks, such as code compilation and debugging, so that you can focus on writing and testing code. Based on the values you pass, different function will be called that serve different purposes.
The author covers a wide range of subjects like electricity, circuits, relays, binary, logic, gates, microprocessors, code, and others to gradually create an understanding of how computer technology works. It is also referred as derived class or a subclass.
