Answer 1

JScrollPane.VERTICAL_SCORLLBAR_AS_NEEDED 与 JScrollPane.HORIZONTAL_SCORLLBAR_AS_NEEDED 错误
确证 JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED 与 JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED
 
scroll 你拼错了 你拼的是 scorll

Answer 2

/*028*/改为：JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED;
/*029*/改为：JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
