Data Structure with Java

Data Structures are ways of organizing, storing, and managing data efficiently so that operations like searching, inserting, deleting, and updating can be performed easily and quickly. In Java, data structures play a very important role in building efficient programs, scalable applications, and optimized algorithms.

 

Understanding data structures helps programmers improve problem-solving skills, write high-performance code, and prepare for technical interviews. Java provides both built-in data structures through the Collection Framework and the flexibility to implement data structures manually using classes and objects.
