Title Body

I have a badly created container object that holds together values of different java types(String, Boolean etc ..) public class BadlyCreatedClass { public Object get(String property) { ...; } }; And we extract values from it in this way String myStr = (String) badlyCreatedObj.get("abc"); Date myDate = (Date) badlyCreatedObj.get("def"); I am forced to write some new code using this object and I am trying to see if there is clean way to do this. More specifically which method from the below is preferred ? Explicit Cast String myStr = (String) badlyCreatedObj.get("abc") Date myDate = (Date) badlyCreatedObj.get("def"); Using generic cast public <X> X genericGet(String property) { } public String getString(String property) { return genericGet(property); } public Date getDate(String property) { return genericGet(property); } Using Class.cast <T> T get(String property, Class<T> cls) { ; } I have gone through several related questions on SO Java generic function: how to return Generic type , Java generic return type all of them seem to say the such typecasting is dangerous, ALthough I dont see much difference between the three, given this which method would you prefer ? Thanks
