如何重构这些包装方法以消除重复代码？

Question

The following two methods are used to wrap deserialization using Google Gson:

public static <T> T Deserialize(String jsonData, Type t) {
    T obj = null;

    try {
        obj = new Gson().fromJson(jsonData, t);
    } catch (Exception e) {
        Log.e(DEBUG_TAG, e.getMessage());
    }

    return obj;
}

public static <T> T Deserialize(String jsonData, Class<T> toClass) {
    T obj = null;

    try {
        obj = new Gson().fromJson(jsonData, toClass);
    } catch (Exception e) {
        Log.e(DEBUG_TAG, e.getMessage());
    }

    return obj;
}

They are almost identical, but I can't figure out a smart way to get rid of the duplicated code.

Any suggestions?

Answer 1

Class implements the interface Type , so it looks like only having the first method should be sufficient.

EDIT: actually it looks like these methods are implemented separately for a reason. At least read the javadoc to understand why before refactoring. Thanks to home for pointing this out.

Answer 2

Type is an interface implemented by Class , so you could get rid of the second method completely.
