Question 3 What is the primary function of the Java compiler (javac)? Converting java source code to bytecode. Running java programs directly. Managing the Java Runtime Environment. Optimizing Java code for performance.

The Java compiler, known as `javac`, is an essential tool that transforms your Java source code, written in `.java` files, into bytecode that runs on the Java Virtual Machine (JVM). This bytecode, typically found in `.class` files, allows Java programs to be platform-independent, enabling them to run on any system that has a JVM installed. So, it's really the magic bridge that turns your human-readable code into something the machine can understand! In real-world applications, this compilation step is crucial for developers. Imagine writing code to create a fabulous app but not being able to run it on different devices. After `javac` does its job, developers can test, debug, and eventually deploy their applications across various platforms seamlessly. This flexibility is one of the many reasons why Java remains a popular choice for building software!
