I'm doing an RBC system to check for similarity between computers. I would like to sort my table rows by the probability value. The problem is that the table has around 9,500,000 rows. Does anyone know how to sort rows by column?

Here is the method I'm using in my code:

package mce;
import java.util.ArrayList;
import java.util.Vector;
import javax.swing.DefaultListModel;
import javax.swing.table.DefaultTableModel;

public class MCE {

public static double  retornaSimGabinete(String a1, String a2){
        if (a1.equals("Full Tower") && a2.equals("Full Tower"))  {
                return 1;
        } else if (a1.equals("Mid Tower") && a2.equals("Mid Tower")) {
                return 1;
        } else if ((a1.equals("Full Tower") && a2.equals("Mid Tower")) || (a2.equals("Full Tower") && a1.equals("Mid Tower"))) {
                return 0.5;
        } else {
            return 0;
        }
}

Crashing when 2nd activity starts I would like to create an object equal to a query in the database

To reorder according to the data in a particular column, you must first implement the getColumnClass of your TableModel , so that the data type of the column you want to sort is known, over there.

You also need to set RowSorter for your table , since it is this class that allows to define a filter and ordering in JTable . Once applied to JTable through setRowSorter , just call toggleSortOrder passing the column as a parameter.

See an example of using RowSorter and toggleSortOrder :

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;

public class RowSorterDemo {

    public void createAndShowGUI() {
        JFrame frame = new JFrame("Sort Table Demo");

        Object rows[][] = {
            {"J", 23},
            {"R", 24,},
            {"E", 21,},
            {"B", 27,},
            {"A", 25,},
            {"S", 22,}};

        String columns[] = {"Name", "Age"};

        TableModel model = new DefaultTableModel(rows, columns) {
            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return Integer.class;
                    default:
                        return Object.class;
                }
            }
        };

        JTable table = new JTable(model);
        //é o RowSorter que ordenará sua tabela
        RowSorter<TableModel> sorter = new TableRowSorter<>(model);
        //aplica o sorter a tabela
        table.setRowSorter(sorter);

        JScrollPane pane = new JScrollPane(table);

        JButton button = new JButton("OrdenarPorIdade");
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                //passa o rowsorter e a coluna da tabela
                //neste caso é a segunda
                reorderingTableByColumn(sorter, 1);
            }
        });

        frame.add(pane, BorderLayout.CENTER);
        frame.add(button, BorderLayout.SOUTH);
        frame.setPreferredSize(new Dimension(300, 200));
        frame.pack();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    private void reorderingTableByColumn(RowSorter sorter, int column) {
        //reordena a tabela pela coluna Age
        sorter.toggleSortOrder(column);
    }

    public static void main(String args[]) {
        EventQueue.invokeLater(new RowSorterDemo().createAndShowGUI());
    }
}

The result of the example is:
