How to avoid casting?
0
$begingroup$
In the main method, I have to call factory to retrieve the Parser and cast it to child parser to read the different file.
How should I improve the code to make it more sense?
public interface Parser<T>{
public Parser read(T t){};
}
public class ParserFromJson implements Parser<JSON>{
@Override
public Data read(JSON json){...};
}
public class ParserFromXml implements Parser<XML>{
@Override
public Data read(XML xml){...};
}
public class ParserFactory{
public Parser create(Type type){
switch(type){
case JSON:
return new ParserFromJson();
case XML:
return new ParserFromXml();
}
}
public enum Type{
JSON, XML
}
public static void main(String args){
((ParserFromJson)ParserFactory.create(JSON)).read(jsonfile);
((ParserFromXml )ParserFactory.create(XML)).read(xmlfile);
}
```
