Unleashing the Power of Map Interface in Java: Efficient Key-Value Data Management

The Map interface in Java is part of the java.util package, and it represents a collection of key-value pairs

[{"selector":"#anim-e42e3581-7a97-422c-987f-7808f937a128 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

It is designed to store information in such a way that each key maps to exactly one value

[{"selector":"#anim-7caeb239-0f1f-4b20-8635-4ddce0f5c555 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

Each key in a Map is one of a kind, and each key maps to exactly one value

[{"selector":"#anim-5f39b7db-f1b3-4a5f-adea-d5a34481ad98 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

Maps are ordinarily used to show associations, such as mapping names to phone numbers, or product IDs to product details

[{"selector":"#anim-d5dfb4a9-8cb9-4151-81e1-859846f159bc [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

HashMap is the foremost broadly used Map implementation

[{"selector":"#anim-a9c8a0ec-7a63-450f-8aee-6e6bad6da80c [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]
