这是我的代码：
- Properties curr_sys=System.getProperties();
- Set<Entry<Object, Object>> s1=curr_sys.entrySet();
- for(Iterator<Map.Entry<Object,Object>> it=s1.iterator();it.hasNext();){
- Map.Entry<Object,Object> m1=it.next();
- Object key=m1.getKey();
- Object value=m1.getValue();
- System.out.println(value+":"+value);
运行结果：
