java - Using InputMismatchException try/catch block -


i want catch input not int , prompt valid input 3 times. after 3 times, program move on , ask rating. can't seem have try/catch block repeat or catch inputmismatchexception. suggestions?

do {     //prompt rating         try {         system.out.println("enter rating between 0-4 movie of week (enter -1 stop/exit): ");         //capture             rating = response.nextint();         } catch (inputmismatchexception err) {             system.out.println("invalid input. please enter rating 0-4 or enter -1 exit: ");             rating = response.nextint();         } //end catch     } while (rating >= 0);

you either in loop:

int count = 0; {     //prompt rating         try {         system.out.println("enter rating between 0-4 movie of week (enter -1 stop/exit): ");         //capture             rating = response.nextint();         } catch (inputmismatchexception err) {             system.out.println("invalid input. please enter rating 0-4 or enter -1 exit: ");             count++;         } //end catch     } while (rating >= 0 && count < 3);

or use nested try/ catch:

do {     //prompt rating         try {         system.out.println("enter rating between 0-4 movie of week (enter -1 stop/exit): ");         //capture             rating = response.nextint();         } catch (inputmismatchexception err) {             system.out.println("invalid input. please enter rating 0-4 or enter -1 exit: ");              try {         system.out.println("enter rating between 0-4 movie of week (enter -1 stop/exit): ");         //capture             rating = response.nextint();         } catch (inputmismatchexception err) {             system.out.println("invalid input. please enter rating 0-4 or enter -1 exit: ");             rating = response.nextint();         } //end catch         } //end catch     } while (rating >= 0);

personally prefer first method.

i tried code , ran without exception:

public class main {

public static void main(string[] args) throws ioexception {     int count = 0;     int rating = 0;     {         scanner response = new scanner(system.in);         //prompt rating             try {             system.out.println("enter rating between 0-4 movie of week (enter -1 stop/exit): ");             //capture                 rating = response.nextint();              } catch (inputmismatchexception err) {                 system.out.println("invalid input. please enter rating 0-4 or enter -1 exit: ");             } {                 count++;                 system.out.println("rating-->" + rating);             }       } while (rating >= 0 && count < 3);  }

}

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
