I want get a list of all the users who are part of public group of the currently logged in user. In documentations, i have read that  able to pick these values from group and group member objects.

A record exists for every User or Group who is a direct member of a public group whose Type field is set to Regular. User records that are indirect members of Regular public groups are not listed as group members. A User can be an indirect member of a group if he or she is in a UserRole above the direct group member in the hierarchy, or if he or she is a member of a group that is included as a subgroup in that group.

Can we get all users of a group using group id? Please help me ASAP it's urgent.
