用Java製作動畫效果

用Java畫動畫很簡單，讓一個線程自己定時調用自己即可，記得要設定一個退出（結束）條件。

import org.eclipse.swt.SWT;import org.eclipse.swt.layout.FillLayout;import org.eclipse.swt.widgets.Display;import org.eclipse.swt.widgets.Shell;import org.eclipse.swt.widgets.Text;public class Animation {    final static int DELAY = 500;    public static void main(String[] args) {        final Display display = new Display();        final Shell shell = new Shell(display);        shell.setLayout(new FillLayout());        final Text text = new Text(shell, SWT.BORDER);        text.setText("0");        new Runnable() {            public void run() {                if (shell.isDisposed())                    return;                text.setText("" + (Integer.parseInt(text.getText()) + 1));                Display.getDefault().timerExec(DELAY, this);            }        }.run();        shell.pack();        shell.open();        while (!shell.isDisposed()) {            if (!display.readAndDispatch())                display.sleep();        }        display.dispose();    }}

運行結果：
