Java
Definition
Java is a high-level, object-oriented programming language that is widely used for developing applications and software. It is known for its platform independence, meaning that programs written in Java can run on any device or operating system with a Java Virtual Machine (JVM).
Analogy
Think of Java as the universal translator of the programming world. Just like how a universal translator allows people from different countries to communicate seamlessly, Java allows developers to write code once and run it anywhere.
