An Overview of Java
Java is a class-based, object-oriented programming that has been around since the mid-1990s. It was designed to be easy to use, lightweight, and suitable for building large-scale applications.
One of the biggest advantages of Java is its principle of “Write Once, Run Anywhere”. This means that you can write Java code on one machine, and it will run on almost any other machine that has a Java Virtual Machine (JVM) installed, regardless of the operating system. This makes Java extremely versatile and useful for cross-platform development.
Java is widely used today for web applications, enterprise software, mobile apps (especially Android), and many other types of programs. Designed for portability, Java is used in millions of applications worldwide, from mobile apps to enterprise app development.
Key Features of Java
Platform Independence: Java’s “write once, run anywhere” philosophy allows applications to run on any device with a Java Virtual Machine (JVM).
Object-Oriented: Java is built around the concept of objects, which represent real-world things. This means that instead of writing code in one big chunk, you create smaller pieces with their own specific functions and data. For example, a “Car” object could have features like colour and speed, and actions like start and stop.
Robust and Secure: Java has built-in features that help find and fix errors in the code before running it, which makes it less likely to crash or have bugs. Java’s memory management system also prevents many common programming errors, making it a reliable choice for building stable applications.Java is known for its security features, which is why it’s commonly used in industries like healthcare and finance.
