log log = new Log(); 那一行老是出现错误
try {
jbInit();
prepareSplash();
startSplash();
Thread splash = new Thread();
splash.sleep(3000);
stopSplash();
mainFrame m = new mainFrame();
log log = new Log();
log.addLog("\r\r","打开了系统");
log.closeStream();
//m.setVisible(true);
}
catch (Exception exception) {
exception.printStackTrace();
}
}

Log log = new Log();
再问：上面说Log cannot be resolved to a type

log log = new Log(); 那一行老是出现错误 log 开机出现在对c:\KAV2007\Log\new\Kawpfw.log进行访问时发生了未知错误 log₂log₃log₄ X=log₃log₄logS log(ab)=log(a)+ log(b)吗 log(27)16/log(3)4= log(10000)/log(10) 函数y=log log(3)4*log(4)8*log(8)M =log(2)16 M是多少 log a b*log b c=log b b*log a c成立吗已知log log求值。
