You didn't provide any context, so all that I can say is that you need to include the library's Jar in your classpath

package view;

import javax.swing.JFrame;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.data.category.DefaultCategoryDataset;

public class NewClass {

public static void main(String[] args) {
    
    // Tạo DefaultCategoryDataset để thêm giá trị của cột
    DefaultCategoryDataset dataset = new DefaultCategoryDataset();
    dataset.addValue(10000, "Doanh thu", "Tháng 1");
    dataset.addValue(12000, "Doanh thu", "Tháng 2");
    dataset.addValue(8000, "Doanh thu", "Tháng 3");
    dataset.addValue(15000, "Doanh thu", "Tháng 4");
    dataset.addValue(20000, "Doanh thu", "Tháng 5");
    
    // Tạo đối tượng JFreeChart
    JFreeChart chart = ChartFactory.createBarChart("Doanh thu hàng tháng", "Tháng", "Doanh thu", dataset);
    
    // Tạo đối tượng ChartPanel để hiển thị JFreeChart
    ChartPanel chartPanel = new ChartPanel(chart);
    
    // Tạo JFrame để hiển thị ChartPanel
    JFrame frame = new JFrame();
    frame.add(chartPanel);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setVisible(true);
}

}

Can you guide me in more detail?

I mean, when you compile, include the path to the jfreechart jar in your classpath argument

#

None of the text you pasted helps with the actual issue

#

Also try googling that error, you'll find something online for it.
