public class Practice07 extends Add07{
private Add0604 add6 =new Add0604();
public static void main(String[] args) {
System.out.println("Practice07.main()");
Practice07 pra6 =new Practice07();
}
public Practice07() {
// TODO Auto-generated constructor stub
System.out.println("Practice07.Practice07()");
}
}

public class Add07 {
Practice021110 pra2 =new Practice021110();
public Practice0302 pra3 = new Practice0302();
private Practice06 pra6 =new Practice06();

public Add07() {
// TODO Auto-generated constructor stub
System.out.println("Add07.Add07()");
}

}

public class Practice06 extends Add0604{

public Practice06() {
// TODO Auto-generated constructor stub
System.out.println("Practice06.Practice06()");
}

}

public class Add0604 implements Practice{

public Add0604() {
// TODO Auto-generated constructor stub
System.out.println("Add0604.Add0604()");
}
}

引用导出类

Practice07.main()

初始化基类（类初始化顺序：先成员函数后构造器）

Practice021110.Practice021110()
Practice0302.Practice0302()
Add0604.Add0604()
Practice06.Practice06()
Add07.Add07()

初始化导出类（类初始化顺序：先成员函数后构造器）
Add0604.Add0604()
Practice07.Practice07()
