这就像读取CSV文件的魅力一样.

就记录损坏的行而言,您可以使用此逻辑来执行此操作.

while(input.hasNextLine())
{
    try 
    {
         //execute commands by reading them using input.nextLine()
    }
    catch (ex: UserDefinedException)
    {
         //catch/log the exceptions you're throwing
         // log the corrupted line the continue to next iteration
    }
}

希望这可以帮助.
