我有一个程序,它有一副牌,洗牌,然后随机获得 10 张牌,并将它们显示在两行中,每行五张。程序编译好了,html页面也编译好了,但是当我运行html页面的时候,appletviewer是空白的……这是为什么呢?
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Image;
public class Cards1 extends Applet{
Image[] image = new Image[52];
public void init() {
image[0] = getImage(getDocumentBase( ),"images/c1.gif");
image[1] = getImage(getDocumentBase( ),"images/c2.gif");
// ...
image[48] = getImage(getDocumentBase( ), "images/h10.gif");
image[49] = getImage(getDocumentBase( ), "images/hj.gif");
image[50] = getImage(getDocumentBase( ), "images/hq.gif");
image[51] = getImage(getDocumentBase( ), "images/hk.gif");
}
public void paint(Graphics g) {
//Shuffle
for (int i = 0; i < image.length; i++) {
int index = (int)(Math.random() * image.length);
Image temp = image[i];
image[i] = image[index];
image[index] = temp;
}
//Display first row
int index = 0;
for(int j = 0; j < 294; j += 71) {
g.drawImage(image[index++], 10 + j, 10, this);
}
//Display second row
index = 5;
for(int j = 0; j < 294; j += 71) {
g.drawImage(image[index++], 10 + j, 106, this);
}
}
}
