4\批处理文件内容如下mobileno.bat

@echo offecho "最近的历史记录~："javac -encoding utf8 "D:\randomMobileNo\GetSourceFileLineNo.java"cd "D:\randomMobileNo\"for /f "delims=" %%i in ('java GetSourceFileLineNo') do (    echo %%i):1echo "请输入渠道：1.蚂蚁开户；2.常规开户；3.保单开户；4.融资融券预开户；5.其他..."javac -encoding utf8 "D:\randomMobileNo\MobileRandomNum.java"cd "D:\randomMobileNo\"for /f "delims=" %%k in ('java MobileRandomNum') do (    echo %%k    echo "%%k" -- %date:~0,10% %time:~0,8%>> result.txt )pausegoto 1

5、执行结果写入result.txt
