使用JAVA的Swt编写代码，能体现到图形化界面上， 这段代码具体内容能使程序产生一个随机数，然后有用户猜（输入数字），猜中胜，记录花费的时间和猜的次数。猜错提示猜大了还是小了，再继续猜，直到猜对为止。

好的，以下是一个基于 SWT 的 Java 程序，实现了你所描述的猜数字游戏：

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.*;

public class GuessNumberGame {
    private Shell shell;
    private Label titleLabel, promptLabel, resultLabel;
    private Text inputText;
    private Button submitButton, restartButton;
    private int answer, guessCount;
    private long startTime;

    public GuessNumberGame() {
        Display display = new Display();
        shell = new Shell(display);
        shell.setText("猜数字游戏");

        GridLayout layout = new GridLayout(2, false);
        shell.setLayout(layout);

        titleLabel = new Label(shell, SWT.NONE);
        titleLabel.setText("猜数字游戏");
        GridData titleData = new GridData(SWT.CENTER, SWT.CENTER, true, false, 2, 1);
        titleLabel.setLayoutData(titleData);

        promptLabel = new Label(shell, SWT.NONE);
        promptLabel.setText("请输入一个 1~100 的数字：");
        GridData promptData = new GridData(SWT.CENTER, SWT.CENTER, false, false, 2, 1);
        promptLabel.setLayoutData(promptData);

        inputText = new Text(shell, SWT.BORDER);
        inputText.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));

        submitButton = new Button(shell, SWT.PUSH);
        submitButton.setText("提交");
        GridData submitData = new GridData(SWT.FILL, SWT.CENTER, false, false, 1, 1);
        submitButton.setLayoutData(submitData);

        resultLabel = new Label(shell, SWT.WRAP);
        resultLabel.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, false, 2, 1)));

        restartButton = new Button(shell, SWT.PUSH);
        restartButton.setText("重新开始");
        GridData restartData = new GridData(SWT.FILL, SWT.CENTER, false, false, 2, 1);
        restartButton.setLayoutData(restartData);
        restartButton.setVisible(false);

        submitButton.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent selectionEvent) {
                try {
                    int guessNumber = Integer.parseInt(inputText.getText().trim());
                    if (guessNumber < 1 || guessNumber > 100) {
                        resultLabel.setText("请输入一个 1~100 的数字！");
                    } else {
                        guessCount++;
                        if (guessNumber == answer) {
                            long endTime = System.currentTimeMillis();
                            long duration = endTime - startTime;
                            resultLabel.setText("恭喜你猜对了！\n共猜了 " + guessCount + " 次，用时 " + duration + " 毫秒。");
                            inputText.setEnabled(false);
                            submitButton.setEnabled(false);
                            restartButton.setVisible(true);
                        } else if (guessNumber < answer) {
                            resultLabel.setText("猜小了！");
                        } else {
                            resultLabel.setText("猜大了！");
                        }
                    }
                } catch (NumberFormatException e) {
                    resultLabel.setText("请输入一个 1~100 的数字！");
                }
            }
        });

        restartButton.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent selectionEvent) {
                startNewGame();
            }
        });

        startNewGame();

        shell.pack();
        shell.open();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
        display.dispose();
    }

    private void startNewGame() {
        answer = (int) (Math.random() * 100) + 1;
        guessCount = 0;
        startTime = System.currentTimeMillis();
        inputText.setText("");
        resultLabel.setText("");
        inputText.setEnabled(true);
        submitButton.setEnabled(true);
        restartButton.setVisible(false);
    }

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

程序会在界面上显示一个输入框和一个按钮，让用户可以输入数字并提交猜测。程序会根据用户猜测的数字与随机生成的答案进行比较，如果猜对了，程序会显示猜测次数和用时，并且禁用输入框和提交按钮，同时显示一个重新开始的按钮。如果猜错了，程序会提示是猜大了还是猜小了，然后让用户继续猜测，直到猜对为止。
