分类：java
何为系统属性？
系统属性是指与用户程序相关的操作系统配置信息以及软件信息。
用户程序相关的属性例子Java代码查看所有系统的属性{(String args[]) {Properties props = System.getProperties();Iterator<Object> iter = props.keySet().iterator();while (iter.hasNext()) {String key = (String) iter.next();System.out.println(key + ” = ” + props.get(key));}}}我本机运行后的结果
