Can a function return two different types?
Using Generics in Java allows you to return a different type, while still retaining static type safety. You simply specify the type that you want to return in the generic type parameter of the function call.
Can a python function return different types?
In Python, you can return multiple values by simply return them separated by commas. In Python, comma-separated values are considered tuples without parentheses, except where required by syntax. For this reason, the function in the above example returns a tuple with each value as an element.

Can a method return more than one result in Java?
No. Java methods can only return one result ( void, a primitive, or an object), and creating a struct -type class like this is exactly how you do it. As a note, it is frequently possible to make classes like your ReturningValues immutable like this:
Is there a way to return different types?
