//Java code only for comparison purpose
package com.agiledeveloper.todo;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.http.ResponseEntity;

@RestController
@RequestMapping("/task")
class TaskController {

  private final TaskService service;

  public TaskController(TaskService service) {
    this.service = service;
  }

  @GetMapping
 ResponseEntity<Iterable<Task>> ...
