# Retrieve Groups

> Retrieve Groups — CometChat documentation.

## Retrieve List of Groups

*In other words, as a logged-in user, how do I retrieve the list of groups I've joined and groups that are available?*

In order to fetch the list of groups, you can use the `GroupsRequest` class. To use this class i.e to create an object of the `GroupsRequest` class, you need to use the `GroupsRequestBuilder` class. The `GroupsRequestBuilder` class allows you to set the parameters based on which the groups are to be fetched.

### Set Limit

This method sets the limit i.e. the number of groups that should be fetched in a single iteration.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    GroupsRequest groupsRequest = new GroupsRequest.GroupsRequestBuilder()
      .setLimit(limit)
      .build();
    ```
  </Tab>
</Tabs>

### Set Search Keyword

This method allows you to set the search string based on which the groups are to be fetched.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    GroupsRequest groupsRequest = new GroupsRequest.GroupsRequestBuilder()
      .setSearchKeyWord("abc")
      .build();
    ```
  </Tab>
</Tabs>

### Joined Only

This method when used, will ask CometChat to only return the groups that the user has joined or is a part of.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    GroupsRequest groupsRequest = new GroupsRequest.GroupsRequestBuilder()
      .joinedOnly(true)
      .build();
    ```
  </Tab>
</Tabs>

### Set Tags

This method accepts a list of tags based on which the list of groups is to be fetched. The list fetched will only contain the groups that have been tagged with the specified tags.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    List<String> tags = new ArrayList<>();
    tags.add("tag1");
    tags.add("tag2");
    GroupsRequest groupsRequest = new GroupsRequest.GroupsRequestBuilder()
    .setLimit(limit)
    .setTags(tags)
    .build();
    ```
  </Tab>
</Tabs>

### With Tags

This property when set to true will fetch tags data along with the list of groups.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    GroupsRequest groupsRequest = new GroupsRequest.GroupsRequestBuilder()
    .setLimit(limit)
    .withTags(true)
    .build();
    ```
  </Tab>
</Tabs>

Finally, once all the parameters are set to the builder class, you need to call the `build()` method to get the object of the `GroupsRequest` class.

Once you have the object of the `GroupsRequest` class, you need to call the `fetchNext()` method. Calling this method will return a list of `Group` objects containing N number of groups depending on the limit set.

The list of groups fetched will only have the public and password type groups. The private groups will only be available if the user is a member of that private group.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    private GroupsRequest groupsRequest = null;
    private int limit = 30;

    groupsRequest = new GroupsRequest.GroupsRequestBuilder().setLimit(limit).build();

    groupsRequest.fetchNext(new CometChat.CallbackListener<List<Group>>() {
      @Override
      public void onSuccess(List <Group> list) {
        Log.d(TAG, "Groups list fetched successfully: " + list.size());
      }
      @Override
      public void onError(CometChatException e) {
        Log.d(TAG, "Groups list fetching failed with exception: " + e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    var groupRequest:GroupsRequest?=null
    val limit:Int=30

    groupRequest=GroupsRequest.GroupsRequestBuilder().setLimit(limit).build()

      groupRequest?.fetchNext(object :CometChat.CallbackListener<List<Group>>(){
        override fun onSuccess(p0: List<Group>?) {
          Log.d(TAG, "Groups list fetched successfully: " + p0?.size)
        }
        override fun onError(p0: CometChatException?) {
          Log.d(TAG, "Groups list fetching failed with exception: " + p0?.message)
        }
      })
    ```
  </Tab>
</Tabs>

## Retrieve Particular Group Details

*In other words, as a logged-in user, how do I retrieve information for a specific group?*

To get the information of a group, you can use the `getGroup()` method.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    private String GUID = "GUID";

     CometChat.getGroup(GUID, new CometChat.CallbackListener<Group>() {
        @Override
        public void onSuccess(Group group) {
        Log.d(TAG, "Group details fetched successfully: " + group.toString());        
        }

        @Override
        public void onError(CometChatException e) { 
         Log.d(TAG, "Group details fetching failed with exception: " + e.getMessage());   
      
     }
         });
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val GUID:String="GUID"

    CometChat.getGroup(GUID,object :CometChat.CallbackListener<Group>(){
      override fun onSuccess(p0: Group?) {
        Log.d(TAG, "Group details fetched successfully: " + p0?.toString())
      }
      override fun onError(p0: CometChatException?) {
        Log.d(TAG, "Group details fetching failed with exception: " +p0?.message)
      }
    })
    ```
  </Tab>
