## Uses of Class
java.lang.Class

Packages that use Class
java.io | Provides for system input and output through data streams, serialization and the file system.
java.lang | Provides classes that are fundamental to the design of the Java programming language.
java.lang.reflect | Provides classes and interfaces for obtaining reflective information about classes and objects.
java.net | Provides the classes for implementing networking applications.
java.security | Provides the classes and interfaces for the security framework.

Uses of Class in java.io

Methods in java.io that return Class
`protected Class` | `ObjectInputStream.resolveClass(ObjectStreamClass v)` Load the local class equivalent of the specified stream class description.
`protected Class` | `ObjectInputStream.resolveProxyClass(String[] interfaces)` Returns a proxy class that implements the interfaces named in a proxy class descriptor; subclasses may implement this method to read custom data from the stream along with the descriptors for dynamic proxy classes, allowing them to use an alternate loading mechanism for the interfaces and the proxy class.
`Class` | `ObjectStreamClass.forClass()` Return the class in the local VM that this version is mapped to.
`Class` | `ObjectStreamField.getType()` Get the type of the field.

Methods in java.io with parameters of type Class
`protected void` | `ObjectOutputStream.annotateClass(Class cl)` Subclasses may implement this method to allow class data to be stored in the stream.
`protected void` | `ObjectOutputStream.annotateProxyClass(Class cl)` Subclasses may implement this method to store custom data in the stream along with descriptors for dynamic proxy classes.
`static ObjectStreamClass` | `ObjectStreamClass.lookup(Class cl)` Find the descriptor for a class that can be serialized.
