Will line 1 give me an error ? If yes, why?

Question

Here's the code
//code from pckg abc
package abc;

class Sup { protected int x;}

//code in pckg xyz
package xyz;
import package abc;

class Sub extends Sup {
psvm (...){ Sup obj=new Sup () //line 1
obj.x=5;}
}

Answer 1

yes, it will give error. Sub classes can access protected members but not through objects
