override fun hashCode(): Int

Returns a hash code value for this integer.

Calling from Kotlin

Here's an example of calling this function from Kotlin code:

// Given
val number: Long = Long.MAX_VALUE
val integer: Integer = Integer.from(number)
// When
val result: Int = integer.hashCode()
// Then
val expected: Int = Integer.from(number)
    .hashCode()
check(result == expected)

Calling from Java

Here's an example of calling this function from Java code:

// Given
final long number = Long.MAX_VALUE;
final Integer integer = Integer.from(number);
// When
final int result = integer.hashCode();
// Then
final int expected = Integer.from(number)
        .hashCode();
final boolean check = result == expected;
if (!check) throw new IllegalStateException("Check failed.");
