Why is Java platform independent?

Java runs on JVM using bytecode, making it platform independent.

Why is Java not fully object oriented?

Because Java supports primitive data types.

Class loader loads class files into memory at runtime.

Compile → Load → Verify → Execute.

Bytecode is intermediate code generated by Java compiler.

Due to bytecode verification, sandboxing, and no direct memory access.

Platform independent, secure, object oriented, multithreaded.

Java source code is compiled into bytecode.

JVM executes code, JRE provides runtime, JDK provides development tools.

JVM loads, verifies, and executes bytecode using interpreter or JIT.

🔹 Core Java & JVM Fundamentals

Java is platform-independent because compiled Java code is converted into bytecode, which can run on any system having a JVM.

The Java compiler converts source code (.java) into bytecode (.class), which is later executed by the JVM.

JVM executes bytecode, JRE provides runtime environment, and JDK includes JRE plus development tools like compiler and debugger.

JVM loads bytecode, verifies it, and executes it using an interpreter or Just-In-Time (JIT) compiler.

Java is not 100% object-oriented because it supports primitive data types like int, char, and boolean.

The class loader loads class files into memory dynamically when they are needed during execution.

Java source code is compiled into bytecode, loaded by class loader, verified, and executed by the JVM.

Bytecode is intermediate code generated by the Java compiler that enables platform-independent execution.

Java is secure due to features like bytecode verification, sandbox execution, class loader isolation, and no direct memory access.

Key features of Java include platform independence, object-oriented design, security, robustness, multithreading, and high performance.
