How to Generate Dummy Data for Java Classes

When building APIs, tests, or prototypes, developers often need mock data that looks real. Instead of typing it manually, you can automate it with the Dummy Data Generator Chrome extension.

1. Install the Extension

Add Dummy Data Generator to Chrome and open it from your toolbar.

2. Paste Your Class Definition

public class User {
  private String name;
  private String email;
  private int age;
}

3. Generate Data Instantly

Click Generate and get structured JSON output like this:

{
  "name": "Alice Johnson",
  "email": "alice.j@example.com",
  "age": 29
}

It’s perfect for testing APIs, mocking backends, or populating sample UI data.
