Collection Framework

Java Collection Framework defines several classes and interfaces to represent group of individual objects as single entity, i.e. Data Structures.

Although, referred to as a framework, it functions more like a library with a collection of classes and interfaces.

💡 Every Collection class is based on some standard data structure.

• All Collection Classes implement Serializable and Cloneable

  • Why though?

    Collections $\equiv$ Containers in C++ → used to transfer

    To transfer object from one place to another, it should be serializable.

    When sent from one place to another, the receiver makes a copy of it and operates on it → clonable
