示例：

　　cellspacing="0" cellpadding="2" bordercolorlight = "black" bordercolordark = "#FFFFFF" align="center"> InputStream in =
　　lnew BufferedInputStream
　　(new FileInputStream(name));
　　Properties p = new Properties();
　　p.load(in);

　　2、使用java.util.ResourceBundle类的getBundle()方法

　　示例：

　　ResourceBundle rb =
　　ResourceBundle.getBundle(name,
　　Locale.getDefault());

　　3、使用java.util.PropertyResourceBundle类的构造函数

　　示例：

　　InputStream in =
　　new BufferedInputStream(new FileInputStream(name));
　　ResourceBundle rb =
　　new PropertyResourceBundle(in);

　　4、使用class变量的getResourceAsStream()方法

　　示例：

　　InputStream in =
　　JProperties.class.getResourceAsStream(name);
　　Properties p = new Properties();
　　p.load(in);

　　5、使用class.getClassLoader()所得到的java.lang.ClassLoader的getResourceAsStream()方法

　　示例：

　　InputStream in =
　　JProperties.class.getClassLoader()
　　.getResourceAsStream(name);
　　Properties p = new Properties();
　　p.load(in);

　　6、使用java.lang.ClassLoader类的getSystemResourceAsStream()静态方法

　　示例：

　　InputStream in =
　　ClassLoader.getSystemResourceAsStream(name);
　　Properties p = new Properties();
　　p.load(in);

　　补充

　　Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream()方法

　　示例：

　　InputStream in =
　　context.getResourceAsStream(path);
　　Properties p = new Properties();
　　p.load(in);
