java atm源代码解析
先不说公司的保密协议
一个项目的代码能在这里全贴出来，还给你讲解的清楚？
、不过整个取款机流程是很简单的，就是用户进行不同的操作，
java 调用 JNI驱动硬件执行相应的操作，关键就是组织各种类型的报文，
通过DTU发送到银联那边，比如说支付报文，冲正报文，日结报文……
这些报文的组织一般java 也只管传入JNI 中C++组装好以后再调用 DTU驱动发送
java 这一块就是处理一些逻辑或者页面流转之类的、
代码是不可能贴的，保密协议还是有一定的约束力的
MyView myView = new MyView();
myView.anyView = this;
this.remove(this.xxPanel);
this.add(myView.getPanel());
this.repaint();
有没有解析java源代码的工具啊
你要看class的？可以用jd-gui.exe 如果要集成在eclipse里面的话，可以用jadClipse

java源代码怎么打开
源代码默认是打不开的，可以使用反编译工具，进行逆向解析才能看到源代码。
eclipse这个开发工具，默认有反编译的插件，在查看的类，按住ctrl点击鼠标左键即可查看源代码。
