我的Runnable Jar文件无法通过双击运行,我正在运行64位Windows和Eclipse.编译时也没有出现任何错误.我不确定这是我的代码还是其他东西.
这是代码.

解决方法:
您的代码没有任何问题-它将编译.
首先,确保您的主类是Cal.java.可以通过右键单击项目的属性-> gt来完成.运行/调试设置->点击一种配置(或进行新的配置)->编辑->选择一个班级.
接下来,确保将项目导出为可运行的JAR文件.可以通过右键单击项目,导出…->来完成.可运行的JAR文件(在Java文件夹下)->下一个->选择与上述相同的配置.
您应该能够双击JAR文件,或者在命令提示符/终端中使用以下命令：java -jar FileName.jar.
那应该解决您的问题.
