提供一段代码可以打印所有的系统属性：

     java.util.Properties pp = System.getProperties();
        java.util.Enumeration en = pp.propertyNames();
        while (en.hasMoreElements()) {
            String elm = (String) en.nextElement();
            System.out.print(elm + " ---->" + pp.getProperty(elm));
            System.out.println();
        }

打印出的所有属性名和值例子：（拿自己的机子做试验）
