java特效java特效代码如何使用

java 程序 跑马灯效果

import java.awt.Color; import java.awt.Dimension; import java.awt.Font; import java.awt.HeadlessException; import java.awt.Point; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.ComponentAdapter; import java.awt.event.ComponentEvent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JViewport; import javax.swing.Timer; public class Test84 extends JFrame { private Timer timer; private JLabel view; private JViewport window; public static void main(String[] args) { JFrame frm = new Test84("跑马灯"); frm.setDefaultCloseOperation(EXIT_ON_CLOSE); frm.pack(); frm.setVisible(true); } public Test84(String title) throws HeadlessException { super(title); initComponents(); addComponentListener(new ComponentAdapter() { public ponentResized(ComponentEvent e) { anchor = new Point(); anchor.x = -window.getExtentSize().width; timer.start(); } }); timer = new Timer(100, new ActionListener() { public void actionPerformed(ActionEvent e) { animate(); } }); timer.setInitialDelay(0); } private void initComponents() { String s = JOptionPane.showInputDialog(null, "请输入要实现效果的文字:"); view = new JLabel(s); view.setFont(Font.decode("Dialog-BOLD-36")); view.setForeground(Color.BLUE); window = new JViewport(); window.setView(view); getContentPane().add(window); } Point anchor; private void animate() { Dimension extSize = window.getExtentSize(); Dimension viewSize = view.getPreferredSize(); anchor.x += 5;//设置移动的速度 window.setViewPosition(anchor); if (anchor.x > viewSize.width) anchor.x = -extSize.width; } }

怎么改变JAVA特效文字的方向

只要在原的代码两个地方加上＋"<br>"就能搞定啦。

改后如下。

楼主可先用查找的方法找到修改的位置： 1.在原代码里查找到text.charAt(i)再在后面加上 +"<br>" 2.在原代码里查找到str += text.charAt(j)再在后面加上 +"<br>"

用java怎么写出滚动效果？

package p; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import java.awt.Font; import java.lang.reflect.InvocationTargetException; import javax.swing.JFrame; import javax.swing.JProgressBar; import javax.swing.SwingUtilities; import javax.swing.border.LineBorder; public class JProgressBarTest extends JFrame { public static void main(String[] args) throws InterruptedException, InvocationTargetException{ Font font=new java.awt.Font("宋体", 0, 12); JProgressBarTest jbt = new JProgressBarTest(); jbt.setTitle("进度条演示"); Container c = jbt.getContentPane(); jbt.setBounds(340,250,200,50); final JProgressBar jpb = new JProgressBar(); jpb.setBorder(new LineBorder(new Color(15,15,15),2)); jpb.setFont(font); jpb.setMinimum(0); jpb.setMaximum(100); Runnable myrun = new Runnable(){ public void run(){ int value = jpb.getValue(); jpb.setValue(value+1); // jpb.setToolTipText("progress"+value+"%"); jpb.setString("progress"+value+"%"); jpb.setStringPainted(true); } }; c.add(jpb,BorderLayout.SOUTH); jbt.setVisible(true); jbt.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); for(int i=0;i<=100;i++){ Thread.sleep(100); SwingUtilities.invokeAndWait(myrun); } } } 如上 ：
