### Intellij IDEA Plugin JsonToPojo Installation and Usage

For converting JSON data into Plain Old Java Objects (POJOs), the `JsonToPojo` plugin is a useful tool within IntelliJ IDEA. The process involves installing this specific plugin from JetBrains' repository or another trusted source.

#### Installing the JsonToPojo Plugin

The installation procedure can be completed through the following method:

1. Open **IntelliJ IDEA**, navigate to **File | Settings** for Windows/Linux users, while macOS users should select **IntelliJ IDEA | Preferences**.
2. In the opened window, go to **Plugins** located under the left-hand menu.
3. Click on the **Marketplace** tab at the top of the plugins list.
4. Use the search bar provided above the plugins list; enter "json to pojo".
5. Once found, click **Install** next to the desired version of the plugin you wish to add.
6. After confirming any prompts about restarting the IDE, proceed with restarting as instructed so changes take effect[^1].

#### Using the JsonToPojo Plugin

After successful installation, generating POJO classes becomes straightforward when working inside an editor session where valid JSON content exists:

- With your cursor placed somewhere over the selected JSON text block,
- Press **Alt+Enter** (Windows/Linux) or **Option+Return** (macOS),
- Choose **Generate POJO(s)** option presented by context actions suggested by the IDE.

This action will open up a dialog allowing customization options such as package name, class names prefix/suffix, target directory among others before finally creating corresponding Java files based upon given input structure.

// Example output after conversion might look like below:
public class User {
    private String firstName;
    private int age;

    public void setFirstName(String firstName){
        this.firstName = firstName;
    }
    
    public String getFirstName(){
        return firstName;
    }

    public void setAge(int age){
        this.age = age;
    }
    
    public int getAge(){
        return age;
    }
}
