A Dialog is a type of modal window which appears in front of app content to provide critical information or ask for a decision. Material UI for React has this component available for us, and it is very easy to integrate. We can create Dialog Box in ReactJS using the following approach.

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command.

cd foldername

Step 3: After creating the ReactJS application, Install the material-ui modules using the following command.

import DialogTitle from "@material-ui/core/DialogTitle";

import DialogContent from "@material-ui/core/DialogContent";
import Button from "@material-ui/core/Button";
  
export default function App() {
  const [open, setOpen] = React.useState(false);
  
  const handleClickToOpen = () => {
    setOpen(true);
  };
  
  const handleToClose = () => {
    setOpen(false);
  };
  
  return (
    <div stlye={{}}>
      <h4>How to create Dialog Box in ReactJS?</h4>
      <Button variant="outlined" color="primary" 
              onClick={handleClickToOpen}>

        <DialogTitle>{"How are you?"}</DialogTitle>
        <DialogContent>
          <DialogContentText>
