java - How to solve ArrayIndexOutofBoundsException -

-

i split string, did not consider exception. error comes out. example, if string "2012-10-21,20:00:00,," 

here codes: string str = "2012-10-21,20:00:00,,"; string a[] = str.split(","); string timestamp = a[0] + "t" + a[1]; string temp = a[2];   system.out.println(timestamp); system.out.println(temp);

here error:

exception in thread "main" java.lang.arrayindexoutofboundsexception: 2

actually, a[2] null, don't know how deal problem. because in string array, recodes contains value of temp, such "2012-10-21,20:00:00,90,".

thank you.

split remove empty elements. need use 2 parameter version:

str.split(",",-1);

see here: java string split removed empty values

-
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...
