Pair

Kotlin |Java

public class Pair
extends Object

java.lang.Object
↳	android.util.Pair<F, S>

Container to ease passing around a tuple of two objects. This object provides a sensible implementation of equals(), returning true if equals() is true on each of the contained objects.

Summary

Fields
`public final F`	`first`
`public final S`	`second`

Public constructors
`Pair(F first, S second)` Constructor for a Pair.

Public methods
`static <A, B> Pair<A, B>`	`create(A a, B b)` Convenience method for creating an appropriately typed pair.
`boolean`	`equals(Object o)` Checks the two objects for equality by delegating to their respective `Object.equals(Object)` methods.
`int`	`hashCode()` Compute a hash code using the hash codes of the underlying objects
`String`	`toString()` Returns a string representation of the object.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Convenience method for creating an appropriately typed pair.

Parameters
`a`	`A`: the first object in the Pair
`b`	`B`: the second object in the pair

Returns
`Pair<A, B>`	a Pair that is templatized with the types of a and b

equals

Added in API level 5

public boolean equals (Object o)

Checks the two objects for equality by delegating to their respective Object.equals(Object) methods.

Parameters
`o`	`Object`: the `Pair` to which this one is to be checked for equality This value may be `null`.

Returns
`boolean`	true if the underlying objects of the Pair are both considered equal

Added in API level 5

public int hashCode ()

Compute a hash code using the hash codes of the underlying objects

Returns
`int`	a hashcode of the Pair

toString

Added in API level 5

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.
