How to set existing bar chart styles to pivot chart in java

Question

I am looking for a way to use apache poi to add existing default styles to a bar chart in Excel. I have code to generate bar chart but could not find anything to set existing styles which are available in Chart Design --> Styles

Below is the current bar chart

Expected outcome

Below is the sample code I am running.

import java.awt.Desktop;
import java.io.File;
import java.io.FileOutputStream;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.ClientAnchor;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFChart;
import org.apache.poi.xssf.usermodel.XSSFDrawing;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.openxmlformats.schemas.drawingml.x2006.chart.*;

public class BarChart {

    public static void main(String[] args) throws Exception {
        Workbook wb = new XSSFWorkbook();
        Sheet sheet = wb.createSheet("Sheet1");

        Row row;
        Cell cell;

        row = sheet.createRow(0);
        row.createCell(0);
        row.createCell(1).setCellValue("HEADER 1");
        row.createCell(2).setCellValue("HEADER 2");
        row.createCell(3).setCellValue("HEADER 3");

        for (int r = 1; r < 5; r++) {
            row = sheet.createRow(r);
            cell = row.createCell(0);
            cell.setCellValue("Serie " + r);
            cell = row.createCell(1);
            cell.setCellValue(new java.util.Random().nextDouble());
            cell = row.createCell(2);
            cell.setCellValue(new java.util.Random().nextDouble());
            cell = row.createCell(3);
            cell.setCellValue(new java.util.Random().nextDouble());
        }

        XSSFDrawing drawing = (XSSFDrawing)sheet.createDrawingPatriarch();
        ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 0, 5, 8, 20);

        XSSFChart chart = drawing.createChart(anchor);

        CTChart ctChart = ((XSSFChart)chart).getCTChart();

        CTBoolean ctBoolean = ctBarChart.addNewVaryColors();
        ctBoolean.setVal(true);
        ctBarChart.addNewBarDir().setVal(STBarDir.BAR);

        for (int r = 2; r < 6; r++) {
           CTBarSer ctBarSer = ctBarChart.addNewSer();
           CTSerTx ctSerTx = ctBarSer.addNewTx();
           CTStrRef ctStrRef = ctSerTx.addNewStrRef();
           ctStrRef.setF("Sheet1!$A$" + r);
           ctBarSer.addNewIdx().setVal(r-2);

           //at least the border lines in Libreoffice Calc ;-)
           ctBarSer.addNewSpPr().addNewLn().addNewSolidFill().addNewSrgbClr().setVal(new byte[] {0,0,0});   

        } 

        //telling the BarChart that it has axes and giving them Ids
        ctBarChart.addNewAxId().setVal(123456);
        ctBarChart.addNewAxId().setVal(123457);

        ctLegend.addNewLegendPos().setVal(STLegendPos.B);
        ctLegend.addNewOverlay().setVal(false);

System.out.println(ctChart);

        FileOutputStream fileOut = new FileOutputStream("BarChart.xlsx");
        wb.write(fileOut);
        fileOut.close();
        Desktop.getDesktop().open(new File("BarChart.xlsx"));
