More knights,liars,and knaves (Posted on 2003-07-07)

Knights always tell the truth,liars always lie,and knaves alternate between truths and lies.

Two people named Jimmy and Johnny make the following claims.

Jimmy:I am a knave.
Johnny:Jimmy is not a knight.
Jimmy:Johnny is a knave.
Johnny:Jimmy is a knave.

What are each?

Since both Johnny's statements are true and they were made in succession, he must be a knight, as a knave would have lied on one of the two statements.
