Starter implementationjava

// How to sort an array of objects in Java
// 1. Validate inputs
// 2. Handle the error path
// 3. Add a test for the edge case you care about

export function solve(input: unknown) {
  // Replace with a minimal working version for sort an array of objects
  throw new Error("Not implemented");
}

What you'll walk away with

By the end of this guide on sort an array of objects java, you should have a working approach, a short checklist for edge cases, and a clear sense of when to reach for a library or free tool instead of hand-rolling everything.

Approach

Confirm your language/runtime version supports the approach below.
