Getting Started with Java

Programming Sachin Nimshan September 15, 2020

Getting Started with Java

To start Java Programming As A Beginner, You need to install Java for your computer. If you already installed Java on your computer, You can check it using the following code.

Open your command prompt and run this code ➡➡ java -version

If You have installed Java, you will get the details of the Java version as below.

If You haven't installed Java in your pc, You can download the Java Development Kit (JDK) from here. (www.oracle.com)

After the Successful installation of Java, You will get the version details as in the above picture.

Now, You can start coding with Java. But in here, I used the Text Editor (Notepad) to write my code in the start. As a beginner for java, you can follow these steps and use notepad to write your codes. However, you can use many other Integrated Development Environment (IDE) for writing java codes which are specially designed for Java programming like Netbeans, IntelliJ IDEA, Eclipse, etc.

Quickstart - How To Run Your First Java Program?

So, Let' start writing our first Java Programme. As I mentioned, I am using Text Editor(Notepad) to write codes. Especially I need to mention that, Every Java Application begins with a Class Name and that Class Name must be matched with the Application's File Name.

STEP 01 - Open Text Editor(Notepad) & write the following code lines.

STEP 02 - Save the Text File as "MyClass.java". Here, I saved it in a folder called Java in my G: drive. You can save it anywhere on your computer.

STEP 03 - Open your command prompt & Navigate to the Directory where you saved your Java File.

STEP 04 - After navigating to the directory, type javac MyClass.java & Enter. This command will compile your code and if there are no errors, you will be redirected to the next line.

STEP 05 - Finally type java MyClass & Enter.

Now, You will See our program is successfully compiled and given the output as "Hello World". Don't Worry, if you don't understand the above code, I will discuss about Java in the next posts for further. However, If you have done this & got the results, Congratulations, You have successfully written and executed your first Java Programme. Keep it Up. See you in the Next Chapter. Thank You.

History & Introduction of Java Language

Programming Sachin Nimshan September 13, 2020

Java is one of the most popular as well as a widely-used programming language in the world now.Java is a high level and object-oriented programming language originally developed by James Gosling in 1995.

He started this "Java Language Project" in 1991 and released the first public implementation in 1995. "Oak" was the first given name for this language but later it was named "Java".

James Gosling

Sun Microsystem released much of Java as free and open-source software under the terms of GNU General Public License (GPL). But on 8th May 2007, Sun Microsystems released Java's core code as free & open-source software property for the public.

What is Java?

Now the Java is owned by Oracle Corporation. Java can be considered as the most used programing language all over the world because 3 Billion devices run using Java.

Java is used for:

Desktop Applications
Mobile Applications (Android)
Web Application
Web Server & Application Servers
Database Connections
Game Developments

Why we use Java?

Java is free & Open Source.
Java can run on any platform (Windows, Linux, Mac, etc).
One of the most popular and widely used languages in the world
Easy to learn and simple to use.
Java users have Huge community support (Millions of developers all around the world).
Java is powerful, secure, and fast.
Java is an object-oriented language, so the programmers can maintain a clear structure within the applications and codes can be reused. (Reduce the code complexity)

Artificial Intelligence - Introduction

Artificial Intelligence Sachin Nimshan September 11, 2020

Artificial Intelligence (AI)

AI stands for Artificial Intelligence. AI becomes a trending topic in the modern world now.

What is Artificial Intelligence (AI)?

In simple, Artificial Intelligence is working machines or computer programs like humans using actions as learning, thinking, and execution. The term, AI can use for any machinery or computer program that performs like the human mind. The main characteristic of Artificial Intelligence is the ability to identify the best accurate solution and taking actions with the best chance to achieve a specific goal.

Understanding AI

When we consider about AI, most of the people have the idea about Robots. Yes, but only for Robots, various AI-powered technologies are also using in the world for different dimensions. The main principle in AI is defining a way that machines or computers can understand as humans and execute tasks from simple to complex using actions like Learning, thinking. You may already know about Machine Learning. Machine Learning can be considered as the core of AI.
