java - The structure of txt file code is reading from -

can please explain why there have 3 empty rows in between sections of text (marked number) in txt file code reading ?

i have code reading lines txt file. structure of file follows:

1
r
line of text
line of text
line of text
line of text
line of text



2
a
line of text
line of text
line of text
line of text
line of text

a number mark m using identify section read. when section identified code reads consecutive lines of text , returned values assigned string variables. works , if there 3 empty rows separating each section of text source txt file. d understand why ? thank much

here's snippet of code:

inpstream = getclass().getresourceasstream("/resources/myfile.txt"); try (bufferedreader reader = new bufferedreader(new inputstreamreader(inpstream,"utf-16be"))){                   do{            num = integer.tostring(a);            line = reader.readline();                                         if(line.equals(num)){              = reader.readline();               = reader.readline();              sat = reader.readline();              pow = reader.readline();              satno = reader.readline();              cash = reader.readline();              break;          }           } while(!line.equals(num) && (line = reader.readline()) != null );    }    catch(ioexception e){} 

it number , order of calls readline().

your code reads , checks every other line match. 3 blank lines not important, it's it's number since first index number. work one, 5 etc.

the double read occurs once @ beginning of each iteration, , once in condition.

line = reader.readline(); 

and

while(... && (line = reader.readline()) != null 

thereby skipping 2 lines each iteration.

i recommend either moving first read out of loop, or change while-loop:

string line; while ((line = reader.readline() != null) {     if (line.equals(num){         ...         break;     } } 

this reads each line, checking against num each line.

defining num can moved out of loop, not change inside loop. giving full example of:

inputstream inpstream = getclass().getresourceasstream("/resources/myfile.txt"); try (bufferedreader reader = new bufferedreader(new inputstreamreader(inpstream, "utf-8"))) {      num = integer.tostring(a);      string line;     while ((line = reader.readline()) != null) {          if (line.equals(num)) {             = reader.readline();             = reader.readline();             sat = reader.readline();             pow = reader.readline();             satno = reader.readline();             cash = reader.readline();             break;         }     }  } catch (ioexception e) { } 

note: example uses utf-8.
