Write about Java Collections Framework and List out some benefits of Collections framework

What is Java Collections Framework? List out some benefits of Collections framework?

Collections are used in every programming language and initial java release contained few classes for collections: Vector, Stack, Hashtable, Array. But looking at the larger scope and usage, Java 1.2 came up with Collections Framework that group all the collections interfaces, implementations and algorithms. Java Collections have come through a long way with usage of Generics and Concurrent Collection classes for thread-safe operations. It also includes blocking interfaces and their implementations in java concurrent package. Some of the benefits of collections framework are: Reduced development effort by using core collection classes rather than implementing our own collection classes. Code quality is enhanced with the use of well tested collections framework classes. Reduced effort for code maintenance by using collection classes shipped with JDK. Reusability and Interoperability
