使用：
在src下新建一个test.properties文件如下：
执行解析：
1publicclass Test { 2 3publicstaticvoidmain(String[] args)throws Exception { 4new ReadProperties() { 5 @Override 6publicvoid dealKeyAndValue(String key, String value) { 7System.out.println(key + " = " + value); 8 } 9}.read("/test.properties");;10 }1112}
结果如下：
