//sampleStart
val array = arrayOf("apples", "oranges", "limes")
val arrayCopy = array.copyOf()
println(arrayCopy.contentToString()) // [apples, oranges, limes]

fun DoubleArray.copyOf(newSize: Int): DoubleArray
(Common source) (JVM source) (JS source) (Native source)
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
(Common source) (JVM source) (JS source) (Native source)
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.

//sampleEnd
}
fun CharArray.copyOf(newSize: Int): CharArray
(Common source) (JVM source) (JS source) (Native source)
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.
