Exam 1z0-808 topic 1 question 233 discussion

we can also access m3, AB is correct but B is complete.

A. t.m1(); Incase you're wondering why we couldn't access m3 even though it's protected and protected methods can be accessed in different package with subclass - " The protected members are inherited by the child classes and can access them as its own members.

package root; public class Tree { public void m1(){} private void m2(){} protected void m3(){} void m4(){} } ------------------------------------------------------------------ package branch; import root.Tree; public class Plant extends Tree{ public void m1(){} public void m2(){} public void m3(){} public void m4(){} public static void main(String[] args){ Tree t = new Plant(); t.m1(); // t.m2(); // t.m3(); // t.m4(); } } Because t is belong to Tree class
