### Reproduce the problem { #reproduce-the-problem }

For most of the cases and most of the questions there's something related to the person's **original code**.

In many cases they will only copy a fragment of the code, but that's not enough to **reproduce the problem**.

Maar helaas krijg je niets bruikbaars:

### Types toevoegen

Laten we een enkele regel uit de vorige versie aanpassen.

We zullen precies dit fragment, de parameters van de functie, wijzigen van:

```Python
    first_name, last_name
```

naar:

```Python
    first_name: str, last_name: str
```

Dat is alles.

Dat zijn de "type hints":

   * accessed directly after this method returns. These conditions are ensured if the map is created
   * empty, passed directly to this method, and no reference to the map is retained, as illustrated
   * in the following code fragment:
   *
   * {@snippet :
   * Set<Object> identityHashSet = Sets.newSetFromMap(
   *     new IdentityHashMap<Object, Boolean>());
   * }
   *
   * <p>The returned set is serializable if the backing map is.

    `NullPointerException`.
 *  New: Recover gracefully when Android's socket connections crash with an
    unexpected `ClassCastException`.
 *  Fix: Don't include the URL's fragment in `encodedQuery()` when the query
    itself is empty.

     * <p>
     * Alternatively {@code getSecurity(true)} may be used to resolve all
     * SIDs together and detect network failures.
