{
//acquire the image
try
{
//我使用的工具是MyEclipse，此处需要读取一张图片，没有任何提示，直接打印出异常日志，要读取图片如何修改呢，请教各位
image = ImageIO.read(new File("blue-ball.gif"));
}
catch(IOException e)
{
e.printStackTrace();
}
}
报错如下：
javax.imageio.IIOException: Can't read input file!

------最佳解决方案--------------------------------------------------------
文件放路径是不是写错了,应该放在在项目下
------其他解决方案--------------------------------------------------------
文件读取错误有两个原因：一是路径，二是该图片不能识别。
楼主，先看看你的路径
------其他解决方案--------------------------------------------------------
应该检查一下你的路径
------其他解决方案--------------------------------------------------------
image = ImageIO.read(new File("blue-ball.gif"));
要么复制图片到你的项目下面，要么修改路径
