java - Error with playing sounds -

-

i have faced error playing sounds on button click in java. have field of buttons , if button pressed application plays sound. application throws me exception:

  javax.sound.sampled.lineunavailableexception: unable obtain line

method , called when button pressed:

public void playsound() {     try {         file file = new file("sounds/sound.wav");         audioinputstream hitstream = audiosystem.getaudioinputstream(file);         audioformat format = hitstream.getformat();         dataline.info info = new dataline.info(clip.class, format);         clip clip = (clip) audiosystem.getline(info);         clip.open(hitstream);         clip.start();     } catch (exception e) {         e.printstacktrace();     } }

sound play @ beginning crashes. googled exception, found clip should closed after playing sound. thought should add lines after clip.start()

if (!clip.isrunning()) {    clip.stop();    clip.close();         }

but sounds don't play , whole application start lag. correct solution error?

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
