Java课程实验代码库-内含源码和说明书(可自己修改).zip

# Java_Experiment 本仓库为Java课程实验代码库 - 仓库下与本文件同层的首层文件夹为实验次数，内层文件夹为实验内题目标号，src文件夹下为工程的java源文件 - 代码使用的 IDE 主要是 Intellij IDEA， 较少时候使用Eclipse，但保证经过了[**阿里巴巴Java开发手册**](https://github.com/alibaba/p3c)的基本要求（部分代码由于题目要求可能并不遵守此规约），运行class文件时带有自定义参数 `-ea` - 代码使用的 JDK 主要是 Oracle JDK 11 和 Open JDK 8 （两个版本均包括但不限于[**AdoptOpenJDK**](https://adoptopenjdk.net/index.html?variant=openjdk11&jvmVariant=hotspot) ,AWS的[**Corretto**](https://github.com/corretto) 和 [**Open JDK**](https://openjdk.java.net/)），不作于任何商业用途。 - 仓库中的代码简记是自己学习的时候整理记录的，借鉴了API和网络的部分内容，以后有时间会考虑写完自己的总结 - 目前PTA的所有题目都完成了AC代码，Java课程做过的PTA题目对应的代码链接如下 > # Java 代码仓库目录 > > > > ## 山东科技大学计算机学院2018年面向对象程序设计（Java） > > 1.
