I want to retrive data in tabular form using ajax and php

I have written the following code

<!DOCTYPE html>
<html lang="en">
<head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-    scale=1.0">
        <title>contact.dat</title>
      <body>
      <div id="demo">
    <h2>Retrive data by ajax</h2>
    <button type="button" onclick="printdata()">Retrive data</button>
    </div>
    
    <script>
    function printdata() {
      const xhttp = new XMLHttpRequest();
      xhttp.onload = function() {
        document.getElementById("demo").innerHTML +=this.responseText;
      }
      xhttp.open("GET", "contact.dat");
      xhttp.send();
    }
    </script>
      </body>
    
    <?php
    
    $fp = fopen('contact.dat', 'r');
    echo "<table border=1>";
    echo "<tr><th>Sr. No.</th><th>Name</th><th>Residence No.</th><th>Mob.
    no.</th><th>Address</th></tr>";
    while ($row = fscanf($fp, "%s %s %s %s %s")) {
        echo "<tr>";
        foreach ($row as $r) {
            echo "<td>$r</td>";
        }
        echo "</tr>";
    }
    echo "</table>";
    fclose($fp);
    ?>
    
    </html>

Here lies the wrong

/usr/bin/env /opt/jdk17/bin/java .... java.ASG6Ba

Probably the file that you try to execute is ASG6Ba.java.

The provided file java.ASG6Ba with the ending ASG6Ba makes no sense for java to be executed.

Also java is a prohibited name for packages in java and since the file provided is java.ASG6Ba, java thinks that java is a package name and then follows the class name ASG6Ba. This is the specific reason the error is thrown.

Prohibited package name: java

This is also described in java documentation in chapter 6.1

The first component of a package or module name must not be the identifier java. Package and module names that start with the identifier java are reserved for packages and modules of the Java SE Platform
