Kotlin 中是否有任何函数可以像在 Java 中那样删除特定范围的元素。

在 Java 中，我们有一个被调用的方法removeRange，它可以被扩展并变得有用。

expect class ArrayList<E> :MutableList<E>,RandomAccess{
    constructor()
    constructor(initialCapacity:Int)
    constructor(elements:Collection<E>)

    fun trimToSize()
    fun ensureCapacity(minCapacity:Int)

   // From List

    override val size:Int
    override fun isEmpty():Boolean
    override fun contains(element:@UnsafeVariance E):Boolean
    override fun containsAll(elements:Collection<@UnsafeVariance E>):Boolean
    override operator fun get(index:Int):E
    override fun indexOf(element:@UnsafeVariance E):Int
    override fun lastIndexOf(element:@UnsafeVariance E):Int

   // From MutableCollection

    override fun iterator():MutableIterator<E>

   // From MutableList

    override fun add(element:E):Boolean
    override fun remove(element:E):Boolean
    override fun addAll(elements:Collection<E>):Boolean
    override fun addAll(index:Int,elements:Collection<E>):Boolean
    override fun removeAll(elements:Collection<E>):Boolean
    override fun retainAll(elements:Collection<E>):Boolean
    override fun clear()
    override …
