Import java.io.BufferedReader;
Import java.io.InputStreamReader;
Import java.net.URL;
Import java.nio.file.Files;
Import java.nio.file.Paths;

        }
    }
    Private static void downloadFile(String fileUrl, String destinationPath) throws Exception {
        Try (BufferedInputStream in = new BufferedInputStream(new URL(fileUrl).openStream())) {
            Files.copy(in, Paths.get(destinationPath));
        }
    }
    Private static void runCommand(String command) throws Exception {
        Process process = Runtime.getRuntime().exec(command);
        Try (BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()))) {
            String line;
            While ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        }
        Int exitCode = process.waitFor();
        If (exitCode != 0) {
            Throw new RuntimeException(“Command execution failed with exit code: “ + exitCode);
        }
    }
}

Here is the example given in python programming language:-

Import os
Import subprocess
Import urllib.request

Print(“Downloading SQL Server 2019…”)
Urllib.request.urlretrieve(download_url, download_path)
Print(f”Downloaded to {download_path}”)
# Define the command for basic installation
Install_command = f”{download_path} /qs /x:SQL2019 /ACTION=Install /FEATURES=SQL,Tools /INSTANCENAME=MSSQLSERVER /SECURITYMODE=SQL /SAPWD=YourStrong!Passw0rd /SQLSYSADMINACCOUNTS=”{os.getlogin()}””
# Run the installation command
Print(“Installing SQL Server 2019…”)
Subprocess.run(install_command, shell=True)
Print(“SQL Server 2019 installation completed.”)
# Download SQL Server Management Studio (SSMS)
