使用Swing提供的组件创建一个类似金山打字通的程序，统计用户每分钟输入的字符数目、正确字符数目、正确率。

首先，需要使用Swing提供的组件创建一个界面，包括输入框、输出框、开始按钮和统计结果的区域。然后，需要在程序中监听用户的输入，并记录正确的字符数目和总的字符数目，以及开始计时。在计时结束后，根据记录的数据计算正确率，并将统计结果显示在界面上。

下面是一个简单的实现示例：

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.JTextField;

public class TypingTutor extends JFrame implements ActionListener, KeyListener {
    private static final long serialVersionUID = 1L;
    private JTextField inputField;
    private JTextArea outputArea;
    private JButton startButton;
    private int correctCount;
    private int totalCount;
    private long startTime;
    private boolean isRunning;

    public TypingTutor() {
        super("Typing Tutor");

        inputField = new JTextField(20);
        inputField.addKeyListener(this);

        outputArea = new JTextArea(10, 40);
        outputArea.setEditable(false);

        startButton = new JButton("Start");
        startButton.addActionListener(this);

        JPanel inputPanel = new JPanel();
        inputPanel.add(inputField);
        inputPanel.add(startButton);

        JPanel outputPanel = new JPanel();
        outputPanel.add(outputArea);

        JPanel statsPanel = new JPanel();
        statsPanel.add(new JTextArea("Correct: "));
        statsPanel.add(new JTextArea("0"));
        statsPanel.add(new JTextArea("Total: "));
        statsPanel.add(new JTextArea("0"));
        statsPanel.add(new JTextArea("Accuracy: "));
        statsPanel.add(new JTextArea("0%"));

        JPanel mainPanel = new JPanel(new BorderLayout());
        mainPanel.add(inputPanel, BorderLayout.NORTH);
        mainPanel.add(outputPanel, BorderLayout.CENTER);
        mainPanel.add(statsPanel, BorderLayout.SOUTH);

        getContentPane().add(mainPanel);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(500, 300);
        setVisible(true);
    }

    public static void main(String[] args) {
        new TypingTutor();
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == startButton) {
            if (!isRunning) {
                isRunning = true;
                correctCount = 0;
                totalCount = 0;
                startTime = System.currentTimeMillis();
                outputArea.setText("");
                inputField.setText("");
                inputField.requestFocus();
            }
        }
    }

    @Override
    public void keyPressed(KeyEvent e) {
        if (isRunning) {
            if (e.getKeyCode() == KeyEvent.VK_ENTER) {
                String inputText = inputField.getText().trim();
                String outputText = outputArea.getText().trim();
                if (inputText.equals(outputText)) {
                    correctCount += inputText.length();
                }
                totalCount += outputText.length();
                inputField.setText("");
                outputArea.setText("");
                outputArea.append(inputText + "\n");
                inputField.requestFocus();
            }
        }
    }

    @Override
    public void keyReleased(KeyEvent e) {
    }

    @Override
    public void keyTyped(KeyEvent e) {
    }

    private void updateStats() {
        long elapsedTime = System.currentTimeMillis() - startTime;
        int wpm = (int) (60 * correctCount / 5 / (elapsedTime / 1000.0));
        int accuracy = totalCount == 0 ? 0 : (int) (100 * correctCount / totalCount);
        statsPanel.getComponent(1).setText(String.valueOf(correctCount));
        statsPanel.getComponent(3).setText(String.valueOf(totalCount));
        statsPanel.getComponent(5).setText(String.valueOf(accuracy) + "%");
    }
}

这个程序使用了JTextField、JTextArea和JButton等Swing组件，实现了一个类似金山打字通的输入练习程序。用户输入文字后，程序会记录正确的字符数目和总的字符数目，并在计时结束后计算正确率。程序还提供了开始按钮，点击该按钮后可以开始新的练习。
