Please tell me how can I implement this API so that I can execute a Java file. we are using Java language to write the program

Getting error code 400 while executing this:

What I have tried:

Thread thread = new Thread(new Runnable() {

u/Override

public void run() {

try {

try {

String clientId = "af52e5b3d******c2d81bade***6c055"; //Replace with your client ID

String clientSecret = "e868414f******183267d398d578a448c6a1a70bf8be2896ebc******b013bc"; //Replace with your client Secret

String script = editText.getText().toString();

String language = "java";

String versionIndex = "0";

URL url = new URL("https://api.jdoodle.com/v1/execute");

HttpURLConnection connection = (HttpURLConnection) url.openConnection();

connection.setDoOutput(true);

connection.setRequestMethod("POST");

connection.setRequestProperty("Content-Type", "application/json");

String input = "{\"clientId\": \"" + clientId + "\",\"clientSecret\":\"" + clientSecret + "\",\"script\":\"" + script +

"\",\"language\":\"" + language + "\",\"versionIndex\":\"" + versionIndex + "\"} ";

System.out.println(input);

OutputStream outputStream = connection.getOutputStream();

outputStream.write(input.getBytes());

outputStream.flush();

if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {

throw new RuntimeException("Please check your inputs : HTTP error code : " + connection.getResponseCode());

}

BufferedReader bufferedReader;

bufferedReader = new BufferedReader(new InputStreamReader(

(connection.getInputStream())));

StringBuilder results = new StringBuilder();

String output1;

System.out.println("Output from JDoodle .... \n");

while ((output1 = bufferedReader.readLine()) != null) {

results.append(output1);

}

connection.disconnect();

output.setText(results);

} catch (IOException e) {

e.printStackTrace();

}

} catch (Exception e) {

e.printStackTrace();

}

}

});

thread.start();
