# Create A Group

> Create A Group — CometChat documentation.

## Create a Group

*In other words, as a logged-in user, how do I create a public, private or password-protected group?*

You can create a group using `createGroup()` method. This method takes a `Group` object as input.

To create an object of `Group` class, you can use either of the below two constructors:

1. `new Group(String GUID, String name, String groupType, String password)`
2. `new Group(String GUID, String name, String groupType, String password, String icon, String description)`

The `groupType` needs to be either of the below 3 values:

1.`CometChatConstants.GROUP_TYPE_PUBLIC` (public)

2.`CometChatConstants.GROUP_TYPE_PASSWORD` (password)

3.`CometChatConstants.GROUP_TYPE_PRIVATE` (private)

    Group group = new Group(GUID, groupName, groupType, password);

    CometChat.createGroup(group, new CometChat.CallbackListener<Group>(){
      @Override
      public void onSuccess(Group group) {
        Log.d(TAG, "Group created successfully: " + group.toString());
      }
      @Override
      public void onError(CometChatException e) {
        Log.d(TAG, "Group creation failed with exception: " + e.getMessage());
      }
    });
    ```

    val groupType:String=CometChatConstants.GROUP_TYPE_PUBLIC
    val password:String=""

    val group=Group(GUID,groupName,groupType,password)

    CometChat.createGroup(group,object :CometChat.CallbackListener<Group>(){
      override fun onSuccess(p0: Group?) {
        Log.d(TAG, "Group created successfully: " + p0?.toString())
      }
      override fun onError(p0: CometChatException?) {
        Log.d(TAG, "Group creation failed with exception: " + p0?.message)
      }
    })
    ```

The `createGroup()` method takes the following parameters:

| Parameter | Description                  |
| --------- | ---------------------------- |
| `group`   | An instance of `Group` class |

After the successful creation of the group, you will receive an instance of `Group` class which contains all the information about the particular group.

<Warning>
  GUID can be alphanumeric with underscore and hyphen. Spaces, punctuation and other special characters are not allowed.
