如何在arraylist的范围内找到最大值或最小值？

Question

I know there is

Collections.max(list);
Collections.min(list);

To get the max or min of an arraylist, but I am looking for a way to get the max or min between a certain range.

For example, what is the max between index 0 and index 5?

Answer 1

Use list.subList to run the operation on a portion of the List :

Collections.max(list.subList(0,6));

list.subList(0,6) returns a view of the portion of the original list between indices 0 and 5 (inclusive).

Answer 2

You can go with sublist. Make a list with range and then pass it as param to the max.

For ex :

Collections.max(list.subList(0,6));
