如题这个答案正确吗？

package com; public class TestParent { protected String protectedStr="protected"; String defaultStr="default"; private void method() { } void abm(){ } protected void proabc(){ } }

package com; public class TestSon extends TestParent{ private void test(){ } }

package com; class Main { static public void main(String[] args) { TestParent parent = new TestParent(); TestSon son = new TestSon(); parent.abm();//default method son.abm();//default method System.out.println(parent.protectedStr); System.out.println(parent.defaultStr); // ------------- parent.proabc(); //protected method son.proabc(); //protected method System.out.println(son.protectedStr); System.out.println(son.defaultStr); } }
