Question

Accepted Answer

Explanation of Java class loading and dynamic class loading.

Java class loaders are responsible for loading classes into the JVM.
There are three types of class loaders: bootstrap, extension, and application.
To run a class in a package, you need to specify the fully qualified name of the class.
Dynamic class loading allows classes to be loaded at runtime instead of compile time.
This can be useful for plugins or modules that are not known at compile time.

Accepted Answer

Class loaders are responsible for loading Java classes during runtime dynamically to the JVM. Also, they are part of the JRE. Hence, the JVM doesn't need to know about the underlying files or file systems in order to run Java programs thanks to class loaders.
