1。使用java.util.Properties类的load()方法示例：InputStreamin=lnewBufferedInputStream(newFileInputStream(name));Propertiesp=newProperties();p.load(in);

2。使用java.util.ResourceBundle类的getBundle()方法示例：ResourceBundlerb=ResourceBundle.getBundle(name,Locale.getDefault());

3。使用java.util.PropertyResourceBundle类的构造函数示例：InputStreamin=newBufferedInputStream(newFileInputStream(name));ResourceBundlerb=newPropertyResourceBundle(in);

4。使用class变量的getResourceAsStream()方法示例：InputStreamin=JProperties.class.getResourceAsStream(name);Propertiesp=newProperties();p.load(in);

5。使用class.getClassLoader()所得到的java.lang.ClassLoader的getResourceAsStream()方法示例：InputStreamin=JProperties.class.getClassLoader().getResourceAsStream(name);Propertiesp=newProperties();p.load(in);

6。使用java.lang.ClassLoader类的getSystemResourceAsStream()静态方法示例：InputStreamin=ClassLoader.getSystemResourceAsStream(name);Propertiesp=newProperties();p.load(in);

补充
Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream()方法示例：InputStreamin=context.getResourceAsStream(path);Propertiesp=newProperties();p.load(in);
