Question

当我尝试在Eclipse上运行我的代码时，会出现以下错误：

Usage: javaw [-options] class [args...]
           (to execute a class)
   or  javaw [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -d32      use a 32-bit data model if available
    -d64      use a 64-bit data model if available
    -server   to select the "server" VM
    -hotspot      is a synonym for the "server" VM  [deprecated]
                  The default VM is server.
