Java – Methods return objects of different types

I’m using gson and Volley to make HTTP GET requests. My idea is to have a method return an object that contains the serialized JSON.

public responseHolder getRequest(){
    Make call
    Parse Json into JsonObject
    return responseHolder;
}

My problem is that I want the method to handle different API calls that return different data. I have 3 classes designed to store 3 different calls and I want the method to return an object of the correct type. Is there a method or design pattern that can help me in this situation, or should I approach it from a different angle?

Maybe try this?

private String getRequest()
{
     Make Call
    return jsonString;
}

public TypeA getA()
{
    return new Gson().fromJson(getRequest(), TypeA.class);
}

public TypeB getB()
{
    return new Gson().fromJson(getRequest(), TypeB.class);
}

public TypeC getC()
{
    return new Gson().fromJson(getRequest(), TypeC.class);
}
