binarySearch
public int binarySearch(float key)
Searches the receiver for the specified value using the binary search algorithm. The receiver must must be sorted (as by the sort method) prior to making this call. If it is not sorted, the results are undefined: in particular, the call may enter an infinite loop. If the receiver contains multiple elements equal to the specified object, there is no guarantee which instance will be found.- Parameters:
key
- the value to be searched for.- Returns:
- index of the search key, if it is contained in the receiver;
otherwise,
(-(insertion point) - 1)
. The insertion point is defined as the the point at which the value would be inserted into the receiver: the index of the first element greater than the key, orreceiver.size()
, if all elements in the receiver are less than the specified key. Note that this guarantees that the return value will be >= 0 if and only if the key is found. - See Also:

Compares the specified Object with the receiver. Returns true if and only if the specified Object is also an ArrayList of the same type, both Lists have the same size, and all corresponding pairs of elements in the two Lists are identical.

mergeSortFromTo
public void mergeSortFromTo(int from, int to)
Sorts the specified range of the receiver into ascending order. The sorting algorithm is a modified mergesort (in which the merge is omitted if the highest element in the low sublist is less than the lowest element in the high sublist). This algorithm offers guaranteed n*log(n) performance, and can approach linear performance on nearly sorted lists.You should never call this method unless you are sure that this particular sorting algorithm is the right one for your data set. It is generally better to call
sort()
orsortFromTo(...)
instead, because those methods automatically choose the best sorting algorithm.- Specified by:
mergeSortFromTo
in classAbstractList
- Parameters:
from
- the index of the first element (inclusive) to be sorted.to
- the index of the last element (inclusive) to be sorted.- Throws:
