Method Detail

copySubList

public static <T> List<T> copySubList(List<T> list,
                                      int fromIndex,
                                      int toIndex)

fromIndex - Starting index in the source List

toIndex - Ending index in the source List

Returns:

a copy of the selected range

IndexOutOfBoundsException - Call exceeds the bounds of the source List
