java - Generic Type Specification for Class Object -

I am using a hashmap and method type changes to the list for the listeners to track the audience is shown below. IDE is giving a warning

  [rawtypes] Raw type found: java.lang.Class Common Category missing type parameter for java.lang.Class & lt; T & gt;  

What kind of class should be specified to address the alert?

  Private Hashmaps  T> cls, ChangeListener listener) {if (class class change listers constants (CLS)) {classChangeListeners.put (CLS, New TreeSet & lt; ChangeListener & gt; ()); } ClassChangeListeners.get (CLS) .add (listener); }    / Code> es which are working with you, instead of  category  instead of  class . 
 
 In some cases, you want to wildcard it,  class  or parametrize it,  class  - But usually  class  will be enough, and it's hard to guess what you really want from a small snippet. 
 
 In addition, it seems that you are using a group with a group. You can use the facility with which this functionality has been built and makes it very good to work with.
