Java enum variables cannot be defined repeatedly in cases?

I need to assign a value to a variable based on the string content, but the variable type is different. I am now

switch (weatherENUM){ case weather: List data = weathreService.getCoviData(reportType); break; case COVI: List data = weathreService.gethelloData(reportType); }

Idea reported an error and repeated the definition. But this is an enumeration and will not be repeated. How do I accomplish my goal?

CoviData and HelloData can inherit the parent class Data at the same time, and use qualified type wildcards to declare objects.
List data. Remember to declare it outside of switch.
