核心代码:如果是默认初始化空容量会走 if (elementData == DEFAULTCAPACITY_EMPTY_ELEMENTDATA) { minCapacity = Math.max(DEFAULT_CAPACITY, minCapacity); }这段代码,接下来基于默认初始化大小10扩容,依次是10,15,22,33这种1.5倍数扩容。如果List<String>list = new ArrayList<>(0);那就是基于你设置的大小0开...
}privatestaticintcalculateCapacity(Object[] elementData,intminCapacity){// 当第一次调用add(E e)方法的时候,判读是不是无参构造函数创建的对象,如果是,// 将DEFAULT_CAPACITY即10作为ArrayList的容量,此时minCapacity = 1if(elementData == DEFAULTCAPACITY_EMPTY_ELEMENTDATA) {returnMath.max(DEFAULT_CAPACITY, ...
在无参构造函数创建ArrayList时其实创建的是一个容量为0的数组(DEFAULTCAPACITY_EMPTY_ELEMENTDATA 标识),只有在第一次新增元素时才会被扩容为10
