java.net.CacheRequest Class in Java

CacheRequest class is used in java whenever there is a need for, storage of resources in ResponseCache. More precisely instances of this class provide an advantage for the OutputStream object to store resource data into the cache, in fact, This OutputStream object is invoked by protocol handlers. CacheRequest class belongs to java.net package along with other classes such as Authenticator, CacheResponse, ServerSocket, SocketAddress, and many more.

Java.Net Package is a container for powerful classes that provides networking infrastructure for java. Now, dwelling onto the two methods present in this class which are as follows:

1. abort() Method
2. getBody() Method

Method 1: abort() Method

It allows cache store operation to be interrupted and abandoned. Hence, it is used for aborting cache response, whenever an IOException occurs current cache operation is aborted. Hence, in simpler words, it aborts the attempt to cache the response.

Syntax : 

public abstract void abort()

Exceptions: It throws IOException if any input-output error is encountered

Method 2: getBody() Method 

It simply returns an InputStream from which the response body can be accessed.

Syntax:

public abstract OutputStream getBody ()

Return Type: OutputStream for which the response should be initiated.

Exceptions: It throws IOException if any input-output error is encountered

Implementation:

Example

The put() method has been initiated and called Successfully!
The put() method returns: null

Finally, we are over with the sheer technical stuff related to this class lets finally do have a peek over the application in the real-world of this class. This class is indirectly used in the daily life of a software person as it provides classes for implementing networking applications in wide versatility.
