推荐答案

String array=new String[];和String array=new String[]{};在Java中都是无效的语句.

String array=new String[]; and String array=new String[]{}; both are invalid statement in java.

它将给您一个错误，您尝试将String array分配给String数据类型. 更具体地说，错误是这样的Type mismatch: cannot convert from String[] to String

It will gives you an error that you are trying to assign String array to String datatype. More specifically error is like this Type mismatch: cannot convert from String[] to String
