2、成， 其中Teacher对象充当监视器，负责给出算术题目，并判断回答者的答案是否正 确；ComputerFrame对象负责为算数题目提供视图，比如用户可以通过 ComputerFrame对象提供的GUI界面看到题目，并通过该GUI界面给出题目的答 案；Ma in Class是软件的主类。（请在下方空白处填写本程序的全部.程序代码及 软件界面截图）import java.awt.*;import java.awt.eve nt*;import javax.sw in g.*;p ublic class Compu terFrame exte nds JFrame JMe nuBar men ub
