诸位帮忙！急！
请大家帮我看看这个秒表程序，为神马秒表的速度会快？？import javax.swing.*;

} --------------------编程问答-------------------- if(onehundredsecond==100){
second++;
onehundredsecond=0;
}
onhundredsecond应该是1000的时候second才加吧
1s=1000ms --------------------编程问答-------------------- 挺好的啊，哪里快了。
分钟:秒:(毫秒/10)
除非这不是你要的显示格式。 --------------------编程问答-------------------- 呵呵，应该是1楼说的那个原因！ --------------------编程问答--------------------
--------------------编程问答-------------------- 同意1楼
