The collection API is the Application Programming Interface and it provided the reusable functionality for a core set of the algorithms that can be operated with the list collections. It has some util packages and it contains some default classes and interfaces that can be required by the collecti...
interface. In essence, algorithms are reusable functionality. Best-known examples of collections framework are the C++ STL and Smalltalk's collection hierarchy. But they are quite complex, which gave them a reputation for having a steep learning curve. Benefits of the Java Collection Framework The ...

Moreover, the collections framework allows us to use a specific data structure for a particular type of data. Here are a few examples, If we want our data to be unique, then we can use the Set interface provided by the collections framework. To store data in key/value pairs, we can ...
