java applection小程序 怎么在paint里面添加图片？？

微信公开课小程序热门讨论「java applection小程序 怎么在paint里面添加图片？？」最新回复-第一种方法：Imageimage=getToolkit().getImage(a.png);第二种方法：URLurl=getClass().getResource(a.png);ImageIconimageIcon=newImageIcon(url);Imageimage=imageIcon.getImage();第三种：Imageimage=imageIO.read(getClass.getClassLoader.getResource(a.png));最后使用画笔对象画就可以了g.drew(图片对象，起点X，起点Y，width，height，null);
