How to Initialize Arrays with Values in Kotlin? - 面试题

In Kotlin, you can use various methods to initialize arrays with specific values. Here are some common approaches:

Using the arrayOf function: This is the most straightforward approach, where you can list all elements directly within the arrayOf function.
```
kotlin
val numbers = arrayOf(1, 2, 3, 4, 5)
```
Using factory functions, such as the Array constructor: If you want to initialize an array with a specific size and values computed by a lambda expression, you can use the Array constructor. This requires the array size and a lambda expression that defines how to compute each element's value.
```
kotlin
val size = 5
val defaultValue = 10
val array = Array(size) { defaultValue }
```
Using specific type arrays like IntArray, DoubleArray, etc.: For primitive types, Kotlin provides specific array types such as IntArray, DoubleArray, etc. These can also be initialized using similar factory methods.
```
kotlin
val intArray = IntArray(5) { 42 }  // Creates an IntArray of size 5 with all elements initialized to 42
```

These methods can be used to initialize arrays with fixed values or dynamically computed values.
