Java Program to Implement RoleUnresolvedList API

This Java program Implements RoleUnresolved API.A RoleUnresolvedList represents a list of RoleUnresolved objects, representing roles not retrieved from a relation due to a problem encountered when trying to access (read or write) the roles.

Here is the source code of the Java Program to Implement RoleUnresolved API.The Java program is successfully compiled and run on a Linux system. The program output is also shown below.
