p.list(fw);//将内存中内容写入到fw的目录文件中
}catch (IOException e){

}
}
结果：
那，我们会发现，生产文件中的内容顺序和我们设定的不一样。因为Properties类实现类map接口，它是用key－value存储数据的，数据也是没有顺序保证的。

public class Main {
public static void main(String[] args) {
Properties p=new Properties();
p.setProperty("IP","127.0.0.1");

try{

}
测试结果：
testPrintToXMLFile
3.2、读取.xml文件里面的内容
testPrintReadFromXMLFile
3.2.2、读取<span style="font-size:14px;">readSteam.xml文件里面的内容：
/**

public class Main {
public static void main(String[] args) throws Exception{
Properties p=new Properties();
FileInputStream fis=new FileInputStream("/Users/cxh/IdeaProjects/JavaBaseTest/src/bin/readStream.xml");
p.loadFromXML(fis);
p.list(System.out);
System.out.println(); //空行
System.out.println("the Mac property is :"+p.getProperty("Mac"));
}
}
输出内容：
the Mac property is :98:73:41:ac:0f:c2
Process finished with exit code 0
