This example demonstrates Hashtable implementing iterators. Like the map classes, Hashtable does not directly support iterators.
This example demonstrates Hashtable implementing iterators. Like the map classes, Hashtable does not directly support iterators.
This example describes Hashtable, that is integrated into the collections framework. It is
This example demonstrates Stack class.
Stack is a subclass of Vector that implements a standard last-in, first-out stack. Stack
Vector implements a dynamic array. It is similar to ArrayList, but with two differences:
Vector is synchronized, and it contains many legacy methods that are not part of the collections framework.
In this example the two versions are shown to defining generic classes with collections.
The first one(in comment) will give compile time error because of it was a legacy syntax.
Java 2 added a new class to java.util called Arrays. This class provides various
methods that are useful when working with arrays. Although these methods technically
The collections framework defines several algorithms that can be applied to collections
and maps. These algorithms are defined as static methods within the Collections class.
This example demonstrates full implementation of custom-comparator.
This program describes more practically TreeMap class that store account balances.
This example describes a custom comparator. If you want to order elements a different way, then specify a Comparator object when you construct the set or map.
This example demonstrates the use of TreeMap class that implements the Map interface by using a tree.
