🛠️ Refactor suggestion

Method name is misleading and doesn't reflect its functionality.

The method name addUsers suggests it adds users to a collection, but it actually extracts user names from a list of users. This violates the principle of clear, self-documenting code.

Rename the method to better reflect its purpose:

-public List<String> addUsers(List<User> users) {
+public List<String> getUserNames(List<User> users) {

🤖 Prompt for AI Agents 
In src/main/java/com/example/demo/DemoApplication.java at line 13, the method
named addUsers is misleading because it does not add users but extracts user
names from a list. Rename the method to something more descriptive like
extractUserNames or getUserNames to clearly reflect its functionality.

List<String> items = new ArrayList<>();
for (User user : users) {
items.add(user.getName());
}
return items;

⚠️ Potential issue

Missing imports will cause compilation errors.

The method uses List, ArrayList, and User classes without proper imports, which will result in compilation failures.

Add the required imports at the top of the file:

 package com.example.demo;
 
+import java.util.ArrayList;
+import java.util.List;
 import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootApplication;

Additionally, ensure the User class is imported if it's not in the same package:

import com.example.demo.User; // Adjust package as needed

the method uses List, ArrayList, and User classes without importing them, which
will cause compilation errors. Add import statements for java.util.List and
java.util.ArrayList at the top of the file. Also, import the User class with the
correct package path if it is not in the same package, for example, import
com.example.demo.User; Adjust the package name as necessary.

💡 Verification agent

🧩 Analysis chain

Verify that the User class exists and has the required getName() method.

The method assumes a User class with a getName() method exists, but this dependency isn't visible in the current codebase context.

🏁 Script executed:

#!/bin/bash
# Description: Verify the User class exists and has getName() method
# Expected: Find User class with getName() method

# Search for User class definition
ast-grep --pattern 'class User {
  $$$
}'

# Search for getName method in User class
ast-grep --pattern 'class User {
  $$$
  $_getName() {
    $$$
  }
  $$$
}'

# Alternative: Search for any User class and getName method
rg -A 10 "class User"
rg -A 5 "getName()"

Length of output: 566

Add or confirm implementation of the User class with a getName() method

It looks like no User class definition was found in the repository, yet DemoApplication.java calls user.getName(). To resolve:

• Create (or import) src/main/java/com/example/demo/User.java in package com.example.demo.
• Ensure it includes:

package com.example.demo;

public class User {
    private String name;
    public User(String name) { this.name = name; }
    public String getName() { return name; }
    // …other fields, setters, etc.
}

• Verify your import in DemoApplication.java matches the User package.

Without a matching User class and getName() method, this code will not compile.

In src/main/java/com/example/demo/DemoApplication.java around lines 13 to 19,
the method addUsers calls user.getName() but there is no User class defined or
imported. To fix this, create a User class in
src/main/java/com/example/demo/User.java with a private String name field, a
constructor that sets name, and a public getName() method returning the name.
Also, ensure DemoApplication.java imports com.example.demo.User so the code
compiles correctly.
