create-folder.java

// Get graph client
IGraphClient client = GraphClient.getClient(tokenProvider);

// Create folder
GraphFolderInfo newFolder = client.createFolder("TEST_FOLDER");

create-subfolder.java

// Get graph client
IGraphClient client = GraphClient.getClient(tokenProvider);

// Create folder inside inbox
GraphFolderInfo newFolder = client.createFolder(GraphKnownFolders.Inbox, "TEST_SUBFOLDER_1");

// Create subfolder inside newly created folder
GraphFolderInfo inboxTestSubFolder2 = client.createFolder(newFolder.getItemId(), "TEST_SUBFOLDER_2");

TokenProvider.java

ITokenProvider tokenProvider = new ITokenProvider() {
    Date expirationDate = null;

    @Override
    public void dispose() {
    }

    @Override
    public OAuthToken getAccessToken(boolean ignoreExistingToken) {
        // Gets oAuth access token.
        // If ignoreExistingToken is true, requests new token from a server. Otherwise behavior is depended on whether token exists or not.
        // If token exists and its expiration date is not expired returns current token, otherwise requests new token from a server.
        return null;
    }

    @Override
    public OAuthToken getAccessToken() {
        // Gets oAuth access token.
        // If token exists and its expiration date is not expired returns current token, otherwise requests new token from a server.
        return new OAuthToken("token", expirationDate);
    }
};

update-folder.java

// Get graph client
IGraphClient client = GraphClient.getClient(tokenProvider);

// Get list of folders
GraphFolderInfoCollection folders = client.listFolders();

// Loop through folders
for (GraphFolderInfo folderInfo : folders) {
    if(folderInfo.getDisplayName()=="TEST_FOLDER")
    {
    	folderInfo.setDisplayName("NEW_TEST_FOLDER");
