Java Buzzword : "Portable" 🤖

Because of its design philosophy, which places a strong emphasis on the maxim "Write Once, Run Anywhere" (WORA), Java is frequently referred to as portable. This mobility is among the most well-known features of Java. We are going to explain it through the storybook example .

So let' s imagine you have a favorite storybook. You can take this storybook with you anywhere and read it – at home, at a friend’s house, or even during a long car ride. Now, Java is a lot like your storybook.

the main storybook is composed to :

• Magic Book (Java Program): When you write a story (or make a program) in Java, it's like writing a magic book. This book is really special because no matter where you take it, the story can be read the same way.
• Magic Glasses (Java Virtual Machine - JVM): To read this magic book, you need a special pair of glasses called the JVM. These glasses let you see the magic in the book. No matter if you're in your room, at the park, or in a different city, as long as you have your glasses, you can see the story. Each place has its own glasses, but they all let you see the same story from your book.
• Universal Language (Platform-Independent Bytecode): The story in your magic book is written in a universal language. That means it doesn’t matter if your friend speaks a different language; with their own pair of magic glasses, they can see the story just like you do.
• Magic Bag (Standardized Java APIs): Imagine you also have a magic bag that you carry with your book. This bag has toys that work the same way no matter where you go. In Java, there are tools that let you do things like drawing pictures or playing music, and they work the same way on any computer.
• Safety Lock (Robust Security Features): Your magic book also has a lock that only lets good people read it. Even if someone who is not supposed to read the book tries, the lock keeps the book safe, so only friends you trust can see the magic story.
• Cleaning Fairy (Garbage Collection): And don’t worry about making a mess! If you leave toys out of your magic bag, a cleaning fairy automatically picks them up and cleans for you, so your room is always nice and tidy.

In other Words and far away from StoryBook example . Java is no "implemetation-dependent " where the size of the primitive data types are specified . For example , an int in Java is always 32-bit integer unlike C/C++ it can be 16-bit integer , 32-bit integer or any size that the compiler likes . Therefore, by fixing the size for number types eliminates a major porting headache .

Because of this, developers can "write once, run anywhere," which streamlines the deployment and development procedures in a variety of computer settings.
