What is the JVM class loading mechanism?

The JVM class loading mechanism is the process by which the Java Virtual Machine loads classes into memory. It involves several steps including loading, linking, and initializing classes.

Can you explain the different phases of class loading?

Sure! The class loading process consists of three main phases: Loading, Linking, and Initialization. Loading involves reading the class file and converting it into a format that the JVM can understand. Linking includes verification, preparation, and resolution. Finally, Initialization is where static variables are assigned and static blocks are executed.

What is the difference between the class loader and the class loading process?

The class loader is a part of the JVM responsible for loading classes, while the class loading process refers to the entire sequence of steps taken to load a class into memory.

Are there different types of class loaders in JVM?

Yes, there are several types of class loaders in the JVM, including the Bootstrap Class Loader, Extension Class Loader, and Application Class Loader. Each has its own role in loading classes from different sources.
