当我编译并运行此代码时:

public class Testing {
    public static void main(String... args) {
        Object obj = null;
        if (obj instanceof Object) {
            System.out.println("returned true"); 
        } else {
            System.out.println("returned false"); 
        }
        System.out.println(" " + obj instanceof Object);
    }
}

我在命令行上看到了这个:

C:\Users\xxxxxx\Desktop>java Testing
returned false
true

不应该"null instanceof someType"总是返回false？
