C++ STL vs Java Collections Framework

Java and C++ provide their different functionalities and their use cases. When it comes to Data structures and Algorithms Java has a special framework named Java collection framework and C++ provides a library called STL.So let's have a look at what are the different functions, complexities, and what are similarities between both of these.

Java Collection Framework 

Java collection provides a framework to store and handle the group of objects and contains an interface named an iterable interface which provides the iterator to iterate through all the collections. A collection is an object that represents a group of objects (such as the classic Vector class). A collections framework is a unified architecture for representing and manipulating collection.

STL in C++ 

The Standard Template Library (STL) is a set of C++ template classes to provide common programming data structures and functions such as lists, stacks, arrays, etc. It is a library of container classes, algorithms, and iterators. It is a generalized library and so, its components are parameterized.

STL has 4 components:

• Algorithms
• Containers
• Functions
• Iterators

C++ provides well-designed STLs, whereas Java has Containers. So have a look at what they both contain.

Those are the major differences between STL and the java collection framework. In terms of using it in competitive programming, one can use any of them as per their convenience as it can make code look less complex and reduce your time to complete a question.
