Introduction To Java Collections Class Methods Youtube
Collections class is a member of the java collections framework. the java.util.collections package is the package that contains the collections class. collections class is basically used with the static methods that operate on the collections or return the collection. all the methods of this class throw the nullpointerexception if the. Java collection class is used exclusively with static methods that operate on or return collections. it inherits object class. the important points about java collections class are: java collection class supports the polymorphic algorithms that operate on collections. java collection class throws a nullpointerexception if the collections or. The java.util.collections class consists exclusively of static methods that operate on or return collections.following are the important points about collections −. it contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed by a specified collection. the methods of this class all throw a. Many of the new methods make use of lambda expressions to simplify operations on collections.these methods make iterating through the collections easier. the developer is freed from actually performing the iteration, and can concentrate only on what happens in each iteration. the advantage is a) easier to read code and b) faster to develop. The following code example shows how to derive a collection class from a constructed type of the collection<t> generic class, and how to override the protected insertitem, removeitem, clearitems, and setitem methods to provide custom behavior for the add, insert, remove, and clear methods, and for setting the item property.

It then displays the names in the collection, and finally empties the collection without disposing of the collection object itself. to see how this works, choose the add class command from the project menu and declare a public variable called instancename at the module level of nameclass (type public instancename ) to hold the names of each. 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.
