How to check is an user has a role on discord

Question

I am struggling to find a way to check if an user has a role. I know how to find a certain role:

public Role findRole(Guild guild, String name) {
    List

The Member object puts a user in the guild context. You can get the member with Guild#getMember(user). This gives you the option to retrieve guild information of this user:

Member member = guild.getMember(user);
Member member = guild.getMemberById(userId);
List member = guild.getMembersByName(name, true);
List member = guild.getMembersByRoles(role);

public Role findRole(Member member, String name) {
    List roles = member.getRoles();
    return roles.stream()
                .filter(role -> role.getName().equals(name)) // filter by role name
                .findFirst() // take first result
                .orElse(null); // else return null
}

Other ways to access a member instance are outlined in the See Also section of the member documentation: Member. Some events also offer a getMember() alternative if the event could happen in a guild context.
