1.getImage(new URL)编译不能通过 | Copy to clipboard |
Posted by: 一枝梅 Posted on: 2005-06-02 08:24 import java.applet.*; import java.net.*; import java.awt.*; public class imag extends Applet{ Image image; public void init() { String url = “http://www.shu.edu.cn/~xyx/img/shnet.jpg“; try { image = getImage(new URL(url)); } catch(Exception e){} } public void paint(Graphics g) { g.drawImage(image, 0, 0,this); } } 以上是我在网上摘抄的,怎么编译出错? |

Posted by: wind520sand Posted on: 2005-06-02 11:51 我查了在JDK1.5的API文档,在Image 没有找到有getImage();方法啊。 到是有个getGraphics();的方法啊 还有上边的类名 imag 应该大写第一个字母啊 Imag 还有就是在String url = "http://www.shu.edu.cn/~xyx/img/shnet.jpg"的引号应该是英文状态下的。而不是中文状态下的啊! 我该了上边的两个错误后,可以运行了。但是什么东西也没有啊! 我不知道这个到底在作什么的? 可以说一下吗? |

Posted by: wind520sand Posted on: 2005-06-02 13:00 我知道了。开始我是查java.awt.image 后来我觉得是不是applet的。我又查了一次找到了!·不过刚才去吃饭了。所以就没及时更新了!呵呵 那么请问。这个是不是显示一图片在APPLET中啊。可是什么都没有啊 |
