请问这题选什么啊?

ClassOne.java
package com.ab.pkg1;
public class ClassOne{
private char var='a';
char getVar(){ return var;}
}

ClassTest.java
package com.ab.pkg2;
import com.ab.pkg1.ClassOne;
public class ClassTest extends ClassOne{
public static void main(String args[]){
char a=new ClassOne().getVar();
char b=new ClassTest().getVar();
}
}
what is the result?
A. Compilation will fail.
B. Compilation succeeds and no exceptions are thrown.
C. Compilation succeeds but an exception is thrown at line 5 in ClassTest.java.
D. Compilation succeeds but an exception is thrown at line 6 in ClassTest.java

A 还是 B ?

B吧。

B!

[longrenrex]

理由呢?

我编译怎么fail啊?

A
他们不是同一个包里，char a=new ClassOne().getVar();
这里会出错，因为在ClassOne，这个方法char getVar(){ return var;}
不是public(无修饰符的时候采用默认级别，只能被其成员和同一个包中其他类可以访问，子类也不可以访问，其他的包是不能访问的）
