JAVA读取ini文件（很简单不带section）

import java.io.*;  
import java.util.Properties;  
  
public class IniReader 
{  
 public  Properties ini = null;  
    public  IniReader(String fileString) 
    {
        File file=new File(fileString);  
        try 
        {  
            ini = new Properties ();  
            ini.load (new FileInputStream (file));  
        }
        catch (Exception ex) 
        {  
            ex.printStackTrace();  
        } 
    }  
 
    public  String getIniKey (String key) {  
        if(!ini.containsKey (key)) 
        {  
            return null;  
        }  
        return ini.get(key).toString();  
    }
    
    public static void main(String[] args)
    {
     IniReader ini=new IniReader("D:\\sendSMS\\conn.ini");
     System.out.println(ini.getIniKey("driver"));
    }
}
