fun LongArray.copyOf(newSize: Int): LongArray

fun FloatArray.copyOf(newSize: Int): FloatArray

fun DoubleArray.copyOf(newSize: Int): DoubleArray

Returns new array which is a copy of the original array, resized to the given newSize. The copy is either truncated or padded at the end with zero values if necessary.

• If newSize is less than the size of the original array, the copy array is truncated to the newSize.
• If newSize is greater than the size of the original array, the extra elements in the copy array are filled with zero values.

//sampleEnd
}

fun BooleanArray.copyOf(newSize: Int): BooleanArray

Returns new array which is a copy of the original array, resized to the given newSize. The copy is either truncated or padded at the end with false values if necessary.

• If newSize is less than the size of the original array, the copy array is truncated to the newSize.
• If newSize is greater than the size of the original array, the extra elements in the copy array are filled with false values.

}

fun CharArray.copyOf(newSize: Int): CharArray

Returns new array which is a copy of the original array, resized to the given newSize. The copy is either truncated or padded at the end with null char (\u0000) values if necessary.

• If newSize is less than the size of the original array, the copy array is truncated to the newSize.
• If newSize is greater than the size of the original array, the extra elements in the copy array are filled with null char (\u0000) values.

fun <T> Array<T>.copyOf(newSize: Int): Array<T?>

fun <T> Array<out T>.copyOf(newSize: Int): Array<T?>

Returns new array which is a copy of the original array, resized to the given newSize. The copy is either truncated or padded at the end with null values if necessary.

• If newSize is less than the size of the original array, the copy array is truncated to the newSize.
• If newSize is greater than the size of the original array, the extra elements in the copy array are filled with null values.
