2nd Chronicles 27:2 points out specifically that Jotham was much like his dad in many ways. That is, he emulated many of his dad's good qualities. But thankfully he didn't try to invade the temple like Uzziah had done. The leprosy of Uzziah was evidently a sufficient warning and a successful preventive measure in warding off any repeat attempt at such nonsense.
So, Jotham intended to live in a way that God could approve of (2nd Chronicles 27:6). And, he did. He didn't live to be an old man and he certainly wasn't perfect (2nd Kings 15:35), but overall, he did ok.
