public class HelloWorld {
    public static void main(String[] args) throws FileNotFoundException {
        Scanner in = new Scanner(Paths.get("E:\\java\\test.txt"));//这一行总是显示//Paths cannot be resolved
        while(in.hasNext())
            System.out.println(in.nextLine());
        in.close();
    }
    static class Paths{
