类型:抽象类java
接口的继承以及实现关系dom
典型方法实现解析this
public List<E> subList(int fromIndex, int toIndex)
将集合从fromIndex到toIndex地方进行剪切public List<E> subList(int fromIndex, int toIndex) { return (this instanceof RandomAccess ? new RandomAccessSubList<>(this, fromIndex, toIndex) : new SubList<>(this, fromIndex, toIndex)); }
SubList
