+# Java 上机报告
+
+这里的是某人的三个Java上机报告源程序，分别为：
+- 继承、抽象类、接口和多态[exp1-oop](https://git.ciduid.top/lensfrex/java-lesson/src/branch/main/exp1-oop/)
+- 多线程及其同步[exp2-thread](https://git.ciduid.top/lensfrex/java-lesson/src/branch/main/exp2-thread/)
+- TCP/UDP和URLConnction的网络[exp3-network](https://git.ciduid.top/lensfrex/java-lesson/src/branch/main/exp3-network/)
+
+项目结构使用Maven管理，Java版本使用Java 8
+.run文件夹是idea的运行配置，使用这些配置能够更方便的在idea进行测试运行
+
+如需手动运行，可以在运行时传入一个参数，指明想要运行的是哪个上机内容，其实不提供也行，可以按照提示手动输入。
+
+已经打包好的jar程序可在[release](https://git.ciduid.top/lensfrex/java-lesson/releases)上获取
+
+项目结构：
+
+<details>
