title: Validated Pairs
---
Added in Fzzy Config 0.6.0
Validation can be joined into pairs, which are stored as a `ValidatedPair.Tuple`. This allows you to present two settings as one, that the user understands are part of the same "unit" of functionality. For example:
* A range with a max and min. Join these together to create one "range" setting that has both two selectors side by side.
* An on-off switch and then an Object/`ValidatedAny` setting with the switch as a [condition](../Validation#-conditional-settings-), building a "confirmation gate" where the user first has to enable the setting before they can interact with it.
Other features:
* Pairs can have labels added to better illustrate what each half of the pair is accomplishing. "Min" and "Max" for the above range example.
* Pair elements can also be stacked on top of each other. See the constructor method below using `ValidatedPair.LayoutStyle.STACKED`.
```java !!tabs Java
//Validated field has a mapping method 'pairWith' that automatically applies the default values of each half into the Pairs default value
public ValidatedPair pair1 = (new ValidatedInt(1, 10, 0)).pairWith(new ValidatedInt(10, 20, 10));
//you can still do it the other way if you want. This also lets you stack the two settings on top of each other if desired.
public ValidatedPair pair1Long = new ValidatedPair(new ValidatedPair.Tuple(1, 10), new ValidatedInt(1, 10, 0), new ValidatedInt(10, 20, 10), ValidatedPair.LayoutStyle.STACKED);
//if both halves are the same validation type, there is a shorthand static method. You can define the default tuple and layout style optionally.
public ValidatedPair pairSame = ValidatedPair.of(new ValidatedInt(1));
//if both halves are the same validation type, there is a shorthand static method. You can define the default tuple and layout style optionally.
public ValidatedPair pairSameLabeled = ValidatedPair.withLabels(ValidatedPair.of(new ValidatedInt(1)), LeftText, RightText);
//Pairs store their value in a nested class `Tuple`. To retrieve your setting you would do something like
int pairMin = pair1.get().left;
int pairMax = pair1.get().right;
```
```kotlin !!tabs Kotlin
//Validated field has a mapping method 'pairWith' that automatically applies the default values of each half into the Pairs default value
val pair1 = ValidatedInt(1, 10, 0).pairWith(ValidatedInt(10, 20, 10))
//you can still do it the other way if you want. This also lets you stack the two settings on top of each other if desired.
val pair1Long = ValidatedPair(ValidatedPair.Tuple(1, 10), ValidatedInt(1, 10, 0), ValidatedInt(10, 20, 10), ValidatedPair.LayoutStyle.STACKED)
//if both halves are the same validation type, there is a shorthand static method. You can define the default tuple and layout style optionally.
val pairSame = ValidatedPair.of(ValidatedInt(1))
//Add labels with the withLabels extension function
val pairSameLabeled = ValidatedPair.of(ValidatedInt(1)).withLabels(LeftText, RightText)
//Pairs store their value in a nested class `Tuple`. To retrieve your setting you would do something like
val pairMin: Int = pair1.get().left
val pairMax: Int = pair1.get().right
