Java.util.collections. public class collections extends object. this class consists exclusively of static methods that operate on or return collections. it contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed by a specified collection, and a few other odds and ends. Java.lang.object. java.util.collections. public class collections extends object. this class consists exclusively of static methods that operate on or return collections. it contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed by a specified collection, and a few other odds and ends. Collection classes should clearly specify in their documentation any restrictions on what elements may be added. if a collection refuses to add a particular element for any reason other than that it already contains the element, it must throw an exception (rather than returning false). this preserves the invariant that a collection always.
