如下代码:

public class Test {
    public int aMethod() {
        static int i = 0;
        i++;
        return i;
    }
    public static void main (String args[]) {
        Test test = new Test();
        test.aMethod();
        int j = test.aMethod();
        System.out.println(j);
    }
}

输出结果是什么？(     )
