使用 java.util.Properties 的奇怪显示
我有一个 .properties 文件，其格式如下：
toto=titi
fofo=fifi
coco=cici
mama=momo
dada=didi
解析此文件时，我的显示很奇怪。这是我正在使用的代码：
Properties prop = new Properties();
String fileLocation = "C:/myProperties.properties";
prop.load(new FileInputStream(fileLocation));
Iterator<Object> it = prop.keySet().iterator();
int line = 0;
while (it.hasNext())
{
String propertyName = (String) it.next();
if (propertyName.equals("coco"))
{
System.out.println("coco found at line : " + line);
break;
}
else if (propertyName.equals("titi"))
{
System.out.println("Titi found at line : " + line);
break;
}
line++;
}
您认为我会输出什么？
我将在您回答后编辑问题。
谢谢。

I'm having a strange display when I parse this file. This is the code I'm using :
Properties prop = new Properties();
String fileLocation = "C:/myProperties.properties";
prop.load(new FileInputStream(fileLocation));
Iterator<Object> it = prop.keySet().iterator();
int line = 0;
while (it.hasNext())
{
String propertyName = (String) it.next();
if (propertyName.equals("coco"))
{
System.out.println("coco found at line : " + line);
break;
}
else if (propertyName.equals("titi"))
{
System.out.println("Titi found at line : " + line);
break;
}
line++;
}
What do you think I will have in output ?
I will edit the question after your answers.
Thank you.

Properties对象由Map实现支持，因此不要依赖属性的顺序。如果您还有其他要报告为“奇怪”的事情，请详细说明您的问题。 :-)Propertiesobject is backed by aMapimplementation so don't rely on the ordering of your properties. If you have something else to report as "strange" please elaborate your question. :-)行号不相关，因为
Properties使用哈希来存储元素。订单不保留。Line number is not relevant as
Propertiesuses hash to store elements. Order is not preserved.
