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();   
   }  

 

运行结果：
