What is the alternative of if statement?-CodePudding

I want to shorten the if conditions. Is there any alternative other than switch case?

 public void check(String name){

        String parentFolder = "";
        

        if(name.matches("birds"))
            parentFolder = birdPFUuid;
        if (name.matches("dogs"))
            parentFolder = dogPFUuid;
        if (name.matches("cats"))
            parentFolder = catPFUuid;
        if (name.matches("vehicles"))
            parentFolder = vehiclesPFUuid;


}

Thank you

    String parentFolder = "";
    parentFolder = (((name.matches("birds"))?"birdPFUuid":
           (name.matches("dogs"))?"dogsFUuid":
            (name.matches("cats"))?"catsFUuid":
            (name.matches("vehicles"))?"vehiclesFUuid":""));

You can use a map data structure to map the parent folder UUID to the dataset name.

Map<String, String> uuidMap = new HashMap<>();
uuidMap.put("birds", birdPFUuid);
uuidMap.put("dogs", dogPFUuid);
uuidMap.put("cats", catPFUuid);
uuidMap.put("vehicles", vehiclesPFUuid);

public void check(String name){
    String parentFolder = uuidMap.get(name);
}
