Answer 1

正如您的问题下面的评论中所指出的，错误的最明显原因是您依赖的资源是使用绝对地址引用的。这基本上意味着您的程序将无效，除非客户端具有与开发计算机完全相同的配置。

要使应用程序可分发，您应该将资源打包到JAR文件中。这个问题有一些有用的指示：

Java Path ImageIcon URL .JAR

另外，在发生异常时抛出的堆栈跟踪在诊断错误时非常有用。你应该把它和任何进一步的问题一起发布在SO上。不要用这样的代码吞下异常：

try {
    doSomethingWhichMightFail();
} catch(Exception e) {

}

除非您完全确定异常无关紧要（这种情况非常罕见！）。
