JAVA INTRODUCTION AND INSTALLATION

JAVA’s LOGO

Java is a programming language initiated by James Gosling in 1995. He initially named the language as ‘oak’ and was not actually contended. Since the oak tree is green, he then switched over the name from ‘oak’ to ‘green’. He loved Java coffee and hence he named the language Java later. This is the reason for the coffee symbol in Java Logo.

Why JAVA?

    When you start learning Java, you become a developer. Around 10 million Java developers are present in this universe.

    Using Java, mobile applications can be emerged easily and nearly 3 billion mobile devices currently function based on this language.

       An average salary that a Java developer gets is roughly 1lakh dollars, however experience from 3 to 4 years in required.

   Recently, Java has emerged exponentially in developing multiple plugins, websites and mobile devices.

   Considering these key features, you can patiently choose whether this language suits you better.

PRE-REQUISITES

Two software tools are mandatory to understand this language.

·      Java JDK

·      IDE

These tools are extensively used in interfacing the program with computer. Java JDK (Java Development Kit) is used in predicting whether the program is properly written (compilation process). IDE (Integrated Development Environment) is used for typing the program.

Few geezers might have complication due to slower processing systems. In such cases, multiple online compilers are present. However, these compliers have potential to compile only smaller process. When it comes to complicated process like application or website development, software tools mentioned earlier is the only course of action.

INSTALLATION OF JAVA JDK 

Step 1:

Open any browser and search Java JDK. I have installed Java using the Oracle website since it’s free. Click JDK download. You will be redirected to another page.

Step 2:

 Depending on your system’s Operating System, you can download the file. Double click the downloaded file and click yes to continue. 

Step 3:

Click Next to continue and then choose your destination folder. It’s recommended to choose C folder and click next again. After the entire installation process is complete, press Close icon.

Step 4:

To check whether the JAVA JDK has installed properly, type java in the command prompt (Run-> Command prompt) and click enter.

On successful installation, you will find some files after typing java else the installation has to be done again.

INSTALLATION OF IDE

·      Search for ‘intelliJ’ in your browser and select the download option in the IntelliJ idea website. 

·   Amidst the two options, ‘ultimate’ option provides advanced features but priceable. However, beginners can utilize community edition which is cost free. Download the .exe file extension. 

·      Double click the installed file once and wait patiently since the speed extensively depends on the system’s speed.

·      Click Yes to continue and then click Next. After choosing the destination folder, click Next again and finally press the continue option and then finish. 

·      To check whether the software has installed properly, type ‘IntelliJ’ in the run menu and wait patiently. Press ‘I agree’ and then next to launch the IDE.

For the proper functioning of the software tools, install them in the same order (JDK first and then IDE).
