遍历Properties中的键值对

 public static void main(String[] args) throws FileNotFoundException, IOException {
  File file = new File("f:");
  Properties tian = new Properties();
  tian.load(new FileInputStream(new File(file,"tian.properties")));
  Iterator it=tian.entrySet().iterator();
  while(it.hasNext()){
      Map.Entry entry=(Map.Entry)it.next();
      System.out.println(entry.getKey().toString()+" = "+entry.getValue());
     
  }
 }
