例子1：
while ((line = reader.readLine()) != null) {
System.out.println(line);
saveToFile(line, "reportlog.log", false);

} else if (getCode(line).equalsIgnoreCase("-2")) {
runresult = "断言错误";
} else {
runresult = "运行成功";
}
}
}
if (line.startsWith("INSTRUMENTATION_STATUS: stack=")) {//截取异常
runinfo = line.substring(30, line.length());
}
if (line.startsWith(" at student.Special.")) {//截取出错行
errorlineinspecial = line.substring(line.indexOf(".")+1, line.length());

errorlineincase = line.substring(line.indexOf(".")+1, line.length());
}
if (line.startsWith(" at student.Library.")) {//截取出错行
