来看看吧 为什么会报错吖

变量i重复定义

public class Test9 {
    private static Scanner scanner = new Scanner(new BufferedInputStream(System.in));
    public static void main(String[] args) {
	    int i = scanner.nextInt();
	    for (int j = 100; j < 1000; j++) {
		    int a = i % 10;
		    int b = i % 10 /10;
		    int c = i / 100;
		    System.out.println(a);
	    }
    }
}

变量名重复了，把其中一个i换成别的就可以
