What tasks does the JVM virtual machine perform during the execution of Java applications?

The Java Virtual Machine (JVM) performs several key tasks when running Java applications:

• Class loading: JVM loads class bytecode from .class files or other sources.
• Bytecode verification: checks the correctness and security of the loaded code.
• Interpretation and compilation: JVM can interpret bytecode or compile it into machine code (JIT compilation) to improve performance.
• Memory management: allocates memory for objects, manages the heap, and performs garbage collection.
• Thread management: supports multithreading and synchronization.
• Exception handling: mechanism for handling errors and exceptional situations.
• Bytecode execution: executes bytecode instructions that implement the program logic.

Thus, JVM provides platform-independent execution of Java applications, abstracting hardware specifics and offering an environment with managed memory and security.
