[java]类初始化挺有意思的题目

public class Base {
    private String baseName = "base";
    public Base() {
        callName();
    }

    public void callName() {
        System.out.println(baseName);
    }

    static class Sub extends Base {
        private String baseName = "sub";
        public void callName(){
            System.out.println(baseName);
        }
    }

    public static void main(String[] args) {
        Base b = new Sub();
        System.out.println(b);
    }
}
