推荐答案

好吧，为了理解上面代码中发生了什么，只需花一些钱关于OOP基础知识的时间，或者如果你有一些背景知识并且仍然无法掌握它，我建议你得到Kathy Sierra的SCJP完整指南，最好是获得java se 8。但是，如果你不愿意花钱来获取它，请参阅java se 6 https://iamgodsom.files.wordpress.com/2014/08/scjp-sun-certified-programmer-对于-Java的6-0071591060.pdf PDF格式。

花一些时间正确阅读它，你的大部分怀疑都会在1或2次读数后被清除。

希望这会有所帮助。

Well, in order to understand as to what's happening in the above code just spend some time on the basics of OOP first or if you have a bit of background of it and are still not able to grasp it then, I'd recommend that you get Kathy Sierra's SCJP complete guide the best would be to get of java se 8. But if you're not willing to spend to get it here's a reference for java se 6 https://iamgodsom.files.wordpress.com/2014/08/scjp-sun-certified-programmer-for-java-6-0071591060.pdfpdf.
Spend some time reading it properly and most of your doubts would get cleared after 1 or 2 readings.
Hope this helps.

上面的代码显示了你提到的所有概念。

你必须掌握 OOP 原则和 Java 编程语言以了解代码。

The above code shows all the concepts you mentioned.
You have to grasp both the OOP principles and the Java programming language in order to understand the code.
