import java.util.*;

class new 
{
    public static void main(String[] args)
    {
        Scanner scanner = new Scanner(Sytem.in);    
        System.out.println("enter a number...");
        int a = scanner.nextInt();
        System.out.println("the number is " + a);
    }
    
}

它在第 3 行抛出一个标识符错误。声明第 3 行需要一个标识符

new.java:3: error:   <identifier> expected
