Google sheets API Batch Update

Could someone please post an example of using Google's batchUpdateValuesRequest to set multiple value on a google sheet?

I am just trying to understand how to change values in a google sheet.

I can successfully authenticate (and read data from a sheet) but am having trouble formatting the update request and its data.

Thanks!

Examples of batch updates can be seen on the link above.

public BatchUpdateSpreadsheetResponse batchUpdate(String spreadsheetId, String title,
                                                  String find, String replacement)
        throws IOException {
    Sheets service = this.service;
    // [START sheets_batch_update]
    List<Request> requests = new ArrayList<>();
    // Change the spreadsheet's title.
    requests.add(new Request()
            .setUpdateSpreadsheetProperties(new UpdateSpreadsheetPropertiesRequest()
                    .setProperties(new SpreadsheetProperties()
                            .setTitle(title))
                    .setFields("title")));
    // Find and replace text.
    requests.add(new Request()
            .setFindReplace(new FindReplaceRequest()
                    .setFind(find)
                    .setReplacement(replacement)
                    .setAllSheets(true)));
    // Add additional requests (operations) ...

    BatchUpdateSpreadsheetRequest body =
            new BatchUpdateSpreadsheetRequest().setRequests(requests);
    BatchUpdateSpreadsheetResponse response =
            service.spreadsheets().batchUpdate(spreadsheetId, body).execute();
    FindReplaceResponse findReplaceResponse = response.getReplies().get(1).getFindReplace();
    System.out.printf("%d replacements made.", findReplaceResponse.getOccurrencesChanged());
    // [END sheets_batch_update]
    return response;
