This Java program Implements RoleList API.A RoleList represents a list of roles (Role objects). It is used as parameter when creating a relation, and when trying to set several roles in a relation (via ‘setRoles()’ method). It is returned as part of a RoleResult, to provide roles successfully retrieved.
Here is the source code of the Java Program to Implement RoleList API.The Java program is successfully compiled and run on a Linux system. The program output is also shown below.
