            int a = Math.abs(cls.getBrowserText().substring(1,3).hashCode()%1000);//产生hashCode
            String key = String.valueOf(a);   
            String Value = cls.getBrowserText            
            map.put(key, Value); //存入key及Value
            System.out.println(map.get(key)); //输出key，不知为何输出的内容却是Value
            //System.out.println("键："+ key + "  值：" + Value); //这里输出key及Value都正常
     }
      
        // Print all resources that have owl:Thing as their rdfs:subClassOf value

        Collection results = owlModel.getRDFResourcesWithPropertyValue(subClassOfProperty, owlThingClass);

            RDFResource resource = (RDFResource) it.next();
            System.out.println(" - " + resource.getBrowserText());
   
        }     

       }

   }

我有问题的是这两行
System.out.println(map.get(key)); //输出key，不知为何输出的内容却是Value
//System.out.println("键："+ key + "  值：" + Value); //这里输出key及Value都正常

如果我要印出hashmap的key及value内容，要如何写呢？..谢谢各位好心人

get指的是得到key的value值，楼主看看java doc就知道了
