我有一个像下面的文件夹结构:
- main
-- java
-- resources
-- scalaresources
--- commandFiles
在那个文件夹中,我有我必须阅读的文件.这是代码:
def readData(runtype: String, snmphost: String, comstring: String, specificType: String): Unit = {
val realOrInvFile = "/commandFiles/snmpcmds." +runtype.trim // these files are under commandFiles folder, which I have to read.
try {
if (specificType.equalsIgnoreCase("Cisco")) {
val specificDeviceFile: String = "/commandFiles/snmpcmds."+runtype.trim+ ".cisco"
val realOrInvCmdsList = scala.io.Source.fromFile(realOrInvFile).getLines().toList.filterNot(line => line.startsWith("#")).map{
//some code
}
val specificCmdsList = scala.io.Source.fromFile(specificDeviceFile).getLines().toList.filterNot(line => line.startsWith("#")).map{
//some code
}
}
} catch {
case e: Exception => e.printStackTrace
} …如何检查所有列表元素是否为负数 - 如果任何单个值为正值则返回false 其他值true？
