Returns true if the two specified arrays of Objects are equal to one another.

[Android.Runtime.Register("equals", "([Ljava/lang/Object;[Ljava/lang/Object;)Z", "")]
public static bool Equals (Java.Lang.Object[]? a, Java.Lang.Object[]? a2);

[<Android.Runtime.Register("equals", "([Ljava/lang/Object;[Ljava/lang/Object;)Z", "")>]
static member Equals : Java.Lang.Object[] * Java.Lang.Object[] -> bool

Parameters

a: Object[]

one array to be tested for equality

a2: Object[]

the other array to be tested for equality

Returns

Boolean

true if the two arrays are equal

Attributes: RegisterAttribute

Remarks

Returns true if the two specified arrays of Objects are equal to one another. The two arrays are considered equal if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal. Two objects e1 and e2 are considered equal if Objects.equals(e1, e2). In other words, the two arrays are equal if they contain the same elements in the same order. Also, two array references are considered equal if both are null.

static member Equals : Java.Lang.Object[] * Java.Lang.Object[] * Java.Util.IComparator -> bool

Parameters

a: Object[]

one array to be tested for equality

a2: Object[]

the other array to be tested for equality

cmp: IComparator

the comparator to compare array elements

Returns

Boolean

true if the two arrays are equal

Attributes: RegisterAttribute JavaTypeParametersAttribute

Remarks

Returns true if the two specified arrays of Objects are equal to one another.

Two arrays are considered equal if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal. In other words, the two arrays are equal if they contain the same elements in the same order. Also, two array references are considered equal if both are null.

Two objects e1 and e2 are considered equal if, given the specified comparator, cmp.compare(e1, e2) == 0.
