Java protected methods access from different instance -

i extending class package when found wasn't compiling, though thought should compile.

i have 2 classes, in different packages. in package com.foobar.a:

package com.foobar.a;  public class {      protected void foo1() {         system.out.println("foo1() called!");     }      protected static void foo2() {         system.out.println("foo2() called!");     }  } 

and in package com.foobar.b:

package com.foobar.b;  import com.foobar.a.a;  public class b extends {      public void bar() {         obj = new a();         obj.foo1(); // doesn't compile         a.foo2(); // compile     }  } 

now, according this: http://docs.oracle.com/javase/tutorial/java/javaoo/accesscontrol.html subclass should able access method, if it's outside same package (and see method being static works). in fact, programming in eclipse , suggestion it's giving me fix issue "change visibility of 'foo1()' protected", it's protected.

so, what's going on here? in oracle specifications indicates access level using class, package, subclass , world. should add "instance" list, , if so, rules be?

if want access method in subclass, can use this:

public void bar() {     this.foo1(); } 

creating object , trying access protected method isn't accessing super class protected method.
