Java MCQ: What is the main function of the Java Virtual Machine (JVM)?

a) To compile Java source code into bytecode
b) To interpret and execute Java bytecode
c) To manage memory allocation in Java
d) To convert Java bytecode into machine code

Answer:

b) To interpret and execute Java bytecode

Explanation:

The Java Virtual Machine (JVM) is responsible for interpreting and executing Java bytecode. Bytecode is the intermediate representation of Java code that is platform-independent. The JVM converts this bytecode into machine-specific code, allowing Java programs to run on any platform that has a compatible JVM.

Additionally, the JVM manages memory, garbage collection, and other runtime aspects of Java programs. It ensures that Java’s “write once, run anywhere” philosophy is maintained.

Understanding the role of the JVM is essential for grasping how Java achieves platform independence and for optimizing Java applications for performance.
