A Simple Java-Based console application that fetches and analyzes a GitHub user's recent public activity using GitHub Rest API

Features

• Accepts a GitHub username as input
• Fetches recent public events using GitHub API
• Parses JSON response using Jackson
• Groups activity by event type
• Tracks count of each event type
• Diplays repository nname associated with the activity

Tech Stack

• Java 21
• Java HttpClient
• Jackson Databind
• Maven

4. Jackson parses JSON into JsonNode
5. Activity types are grouped and counted
6. Results are printed to console

PushEvent 4 octocat/Hello-World
WatchEvent 2 octocat/Spoon-Knife
CreateEvent 1 octocat/Test-Repo
