    I suggest to create a new Tuple2 for the swap, because your current solution only works
because of type erasure.
    
    The following would not work:
    
    ```java
    Tuple2<String, Integer> classUnderTestTuple2 = new Tuple2<String, Integer>(new
String("Test case"), 25);
    classUnderTestTuple2.swapValues();
    
    String s1 = classUnderTestTuple2.f1; // does not work
    Integer i1 = classUnderTestTuple2.f0; // does not work
    ```
    
    So for swapValues() you would do something like `new Tuple2<T1, T0>(T1, T0)`.
