ArrayList.rangeCheck介绍

[英]Checks if the given index is in range. If not, throws an appropriate runtime exception. This method does not check if the index is negative: It is always used immediately prior to an array access, which throws an ArrayIndexOutOfBoundsException if index is negative.
[中]检查给定索引是否在范围内。如果不是,则引发适当的运行时异常。此方法检查索引是否为负:它总是在数组访问之前立即使用,如果索引为负,则会引发ArrayIndexOutOfBoundsException。
