请问操作记录(report)如何编写
我有个作业,最后的要求是Reports:
• If a tank runs dry, display that status in red.
• Log all activity to the Console (p. 193 in the text). This means a log record for each click, each double-click, and for each updating of the tank displays, and for empty tanks.
Record format: Date Time Message, as YYY-MM-DD HH::MM:SS <String>. Some clicks produce several messages.
For no extra marks, but for satisfaction:
• Display vertically, graphically, scales which show how full the tanks are, in % (100 * volume /capacity, rounded meaningfully, e.g. to 0.5 l).
请问如何插入操作记录??
