java - How do I repeat a string in jgrasp without using a loop -


i cannot find way make repeat in way looks 

 xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx 
import java.util.scanner; public class square {     public static void main (string [] args)     {         scanner kb = new scanner (system.in);         system.out.print("enter positive integer no greater 15: ");         double square= kb.nextdouble();         double k=1;         string i= "";         while (k<square+1)         {             k++;             i=i+"x";         }     } }

the final output has letters x in square type formation if enter 8 square variable 8 across , 8 down. knew outcome of going wrong dont know hot make appear above. output looks like

 x xx xxx xxxx xxxxx xxxxxx xxxxxxx xxxxxxxx

if i'm using 8 square

use second loop. construct string in first loop, , print repeatedly in second. or nest 1 loop inside , print characters inner loop, lines outer one.

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
