JAVA从文本文件中找到几个单词或短语并显示出来

Question

当我反向/反向输入词组时，我在查找词组时遇到了一些问题。例如我在找约翰·洛夫洛克的名字和姓氏。程序找到短语并显示给我。我找不到那根火柴，但我找到了。我怎样才能获得这种功能

以下是我得到的：

public class Programa extends JFrame implements ActionListener {
    private JTextArea text;

    public static void main(String[] args) {
        new Programa().setVisible(true);
    }

    public Programa() {
        super("Redagavimas");
        setSize(600, 600);
        setResizable(false);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        initialize(); 

        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {


                JFrame frame = new JFrame("Paieska sarase");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new Layout());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);


            }
        });
    }

    public void initialize(){

        text = new JTextArea();
        JScrollPane scroll = new JScrollPane(text);

        JMenuBar bar = new JMenuBar();
        JMenu file = new JMenu("Failas");
        JMenuItem open = new JMenuItem("Atidaryti");
        JMenuItem save = new JMenuItem("Issaugoti");
        JMenuItem exit = new JMenuItem("Uzdaryti");

        JMenuItem[] items = { open, save, exit};
        for(JMenuItem item : items) {
            item.addActionListener(this);

        }

        file.add(open);
        file.add(save);
        file.addSeparator();
        file.add(exit);

        bar.add(file);

        add(scroll);
        setJMenuBar(bar);
    }

也许你应该考虑使用这个{{CD1}}代替这个^ {< CD2>}，因为这将允许你只使用名称或姓氏搜索。此外，为了使用更改的顺序进行搜索，您应该在代码中处理此问题。虚拟解决方案如下所示，当然会有更好的解决方案：

            public void actionPerformed(ActionEvent e) {
            vieta.removeAllElements();

            String searchText = findText.getText();
            String[] words = searchText.split(" ");

            StringBuilder sb = null;
            if(words.length > 1) {
                sb = new StringBuilder();
                sb.append(words[1]).append(" ").append(words[0]);
            }

            try (BufferedReader reader = new BufferedReader(new     FileReader(new File("sarasas.txt")))) {

                String text = null;
                while ((text = reader.readLine()) != null) {

                    if (text.contains(searchText) || (sb != null && text.contains(sb.toString()))) {

                        vieta.addElement(text);

                    }

                }

            } catch (IOException ee) {

                ee.printStackTrace();
                JOptionPane.showMessageDialog(Layout.this, "No file", "Error", JOptionPane.ERROR_MESSAGE);

            }
        }
