(在创建List对象的时候,使用了Arrays.asList()方法,从其实现源码可以看出,该方法创建的ArrayList对象其实是Arrays类内部自带的,所以在debug跟踪源代码的时候,进入的是Arrays内部的ArrayList对象。简单说就是用Arrays.sort创建的ArrayList对象) OK,发现里面调用的Arrays.sort(a, c); a是list,c是一个比较器,我们来看...
for example, an array backing the arraylist . moreover, we can decide to sort by different conditions each time or even not to sort at all. 3. why sorting on insertion breaks the list contract sorting on insertion would break the contract of the list interface. the contract of the list...
在Kotlin中,arrayListOf()是一个用于创建可变数组列表的函数,它类似于Java中的ArrayList。sortedWith和compareBy是用于排序列表的方法,它们提供了一种简洁的方式来定义排序规则。 基础概念 arrayListOf(): 这是一个Kotlin标准库函数,用于创建一个可变的ArrayList。
