Not working react code

1 
import React, { Component } from "react";

class ProductDetails extends Component {

  handleSave = () => {
    // Navigate to /products
  };

  render() {

    return (
      <div>
        <h1>Product Details - {this.props.match.params.id} </h1>
        <button onClick={this.handleSave}>Save</button>
      </div>
    );
  }
}

export default ProductDetails;

In the above code this.props.match.params.id is not getting the data ?
