J.6 Collections Methods

Class Collections provides several high-performance algorithms (Fig. J.5) for manipulating collection elements. The algorithms are implemented as static methods. The methods sort, binarySearch, reverse, shuffle, fill and copy operate on Lists. Methods min, max and addAll operate on Collections.

Fig. J.5 Some methods of class Collections.
