Why is Java considered platform-independent?

Because Java programs compile to bytecode that can run on any device with a JVM, regardless of the underlying hardware or OS.

What is the role of the JVM in Java's portability?

The JVM interprets Java bytecode on different platforms, enabling the same code to run anywhere.

What makes Java platform-independent?

Java programs are compiled into bytecode, which can run on any device with a Java Virtual Machine (JVM). This means you can write code once and run it anywhere without changing it.

How does Java support object-oriented programming?

Java uses objects and classes to organize code, promoting modularity and reusability. This approach helps in building maintainable and scalable applications.

What features help Java handle errors and security?

Java performs early error checking during compilation and runtime checks like bytecode verification. These features make Java robust and provide a secure environment for running applications.
