class App extends Component {

                  </Button>
                </p>
              </Col>
            </Row>
          </Container>
        </Jumbotron>
      </div>
    );
  }
}

export default App;

And also I have this error

Failed to compile.

./src/index.js
Module not found: Can't resolve 'bootstrap/dist/css/bootstrap.min.css' in 'D:\React\my-app2\src'

Can we use Col or Container on first line instead of div?

To all who're saying bootstrap.css not working. Just import the file at the very first line and it'll work See the example below
import 'bootstrap/dist/css/bootstrap.css';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
