input - a function that returns false as soon as there is a sound detected from the mic (java)

I wanted to know if there is a way to make a function in java that returns false as soon as there is no sound coming from your mic.

I wanted to use it inside a while loop like this :

long timeStart = System.nanoTime();
while (!soundFromMic()) {


                    long timeEnd = System.nanoTime();
                     if (timeEnd - timeStart >= 2000000000) {
                        System.out.println("Time ended and there was no sound detected from mic");
                        break;

                    }

                }
.....

How I think the function would look like:


public static boolean soundFromMic() {
        if (there is sound) {
            return true;
        } else
            return false;

    }

Yes sure! There is something called TargetDataLine. This is an interface and it extends DataLine. Just register an object and it will be receiving events! It's also interesting for me so anyone - WHO KNOWS DETAILS HOW TO IMPLEMENT THIS SHEET?
