java载入图片找不到url，报空指针异常

img

是我没把图片放对文件夹么？


image = Toolkit.getDefaultToolkit().getImage(Panel.class.getResource("/xiuxiu.gif"));

运行后


Exception in thread "main" java.lang.NullPointerException: Cannot invoke "java.net.URL.toString()" because "url" is null

    at com.practice.tank.TankGame.<init>(TankGame.java:11)
    at com.practice.tank.TankGame.main(TankGame.java:7)

你直接复制到out目录下的？


new ClassPathResource("xiuxiu.gif")

重启能解决一半的问题
