滚动数组java代码 滚动数组思想

用java生成一个1到10十个数字随机排列的数组代码如下
import java.util.ArrayList;
public class ArrayListToAry {
public static void main(String[] args) {
//数组
int[] ary = new int[10];
//集合
ArrayListInteger list = new ArrayListInteger();
//给集合添加1~10滚动数组java代码的数字
for (int i = 1; i11; i) {
list.add(i);
}
//循环10次滚动数组java代码 , 随即抽取集合滚动数组java代码的数字给数组
for (int i = 0; i10; i) {
ary[i] = list.get((int)(Math.random()*10));
}
///输出数组滚动数组java代码的元素
System.out.print("数组的元素:");
for (int i = 0; iary.length; i) {
System.out.print(ary[i] " ");
}
}
}
添加JAVA表格代码中的滚动条,纵向的和横向的都添加一下其实JScrollPane滚动条是自动的 , 当你的内容大于容器大小时滚动条就会出现 。
如果你非要滚动条显示,就加上这两句:
jScrollpane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
jScrollpane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
用Java编写一个字符串循环滚动的程序java里面有一个叫做Timer滚动数组java代码的东西
代码找到滚动数组java代码了:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
////////////////////////////////////////////////////////////
public class AnimationDemo extends JFrame{
AnimationDemo(){
add(new MPanel("我是要移动的文字"));
}
////////////////////////////////////////////////////////////
public static void main(String[] args){
JFrame frame=new AnimationDemo();
frame.setTitle("AnimationDemo");
frame.setSize(280, 100);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
/////////////////////////////////////////////////////////////
static class MPanel extends JPanel{
private String message="welcome to java!";
private int xZuoBiao=0;
private int yZuoBiao=30;
//...........................................................
public MPanel(String message){
this.message=message;
Timer timer=new Timer(100,new TimerListener());
timer.start();
}
//............................................................
protected void paintComponent(Graphics g){
super.paintComponent(g);
if(xZuoBiaogetWidth()){
xZuoBiao=-20;
}
xZuoBiao =10;
g.drawString(message, xZuoBiao, yZuoBiao);
}
//.............................................................
class TimerListener implements ActionListener{
public void actionPerformed(ActionEvent e){
repaint();
}
}
}
}
滚动的小球 java源代码;

要制造那种效果只需要大约 30 行 Java 代码:
import javax.swing.*;
import java.awt.*;
import java.awt.geom.*;
class RollingBall extends JPanel {
Ellipse2D.Float ball = new Ellipse2D.Float( -100, 100, 50, 50 );
public void paintComponent( Graphics g ) {
super.paintComponent( g );
Graphics2D g2 = ( Graphics2D ) g;
// Draw the ball
g2.fill( ball );
// Draw the rotating ellipse by skewing the Device Space
double angdeg =// One rotation per ball's travelling over its perimeter
ball.x% ( Math.PI * ball.width ) / ( Math.PI * ball.width ) * 360;
g2.rotate( Math.toRadians( angdeg ), ball.getCenterX( ), ball.getCenterY( ) );
g2.scale( .5, 1 );
g2.translate( ball.getCenterX( ), 0 );
g2.setColor( Color.gray );
g2.fill( ball );
}
public void roll( ) throws Exception {
while( true ) {
repaint( );
Thread.sleep( 8 );
}
}
public static void main( String[ ] args ) throws Exception {
JFrame f = new JFrame( );
RollingBall rb = new RollingBall( );
f.setSize( 999, 185 );
f.getContentPane( ).add( rb );
f.setVisible( true );
rb.roll( );
}
}
