java - How to split the strings in a file and read them? -

i have file information in it. looks like:

    michael 19 180 miami     george 25 176 washington     william 43 188 seattle 

i want split lines , strings , read them. want like:

    michael     19     180     miami     george     ... 

i used code this:

    bufferedreader in = null;     string read;     int linenum;     try{         in = new bufferedreader(new filereader("fileeditor.txt"));      }     catch (filenotfoundexception e) {system.out.println("there problem: " + e);}     try{         (linenum = 0; linenum<100; linenum++){             read = in.readline();             if(read == null){}              else{                 string[] splited = read.split("\\s+");                 system.out.println(splited[linenum]);            }        }     }     catch (ioexception e) {system.out.println("there problem: " + e);}  } 

what gave me

i think issue loop i'm not advanced in programming , i'll appreciate help. thanks.

you're part way there great.

when reading file, reader return null when reaches end of stream, meaning nothing else available read. current approach means want read @ least 100 lines, no more...this become problematic in future if file size increases...it's wasteful

instead, should use fact null value indicates end of file..

when split line, contain number of elements. using linenum variable print these. problem is, you've read , split line, linenum irrelevant task, represents number of lines you've read, not part of string you've split.

instead, need use inner loop display individual split elements each line...

for example...

bufferedreader in = null; try {     in = new bufferedreader(new filereader("fileeditor.txt"));     string read = null;     while ((read = in.readline()) != null) {         string[] splited = read.split("\\s+");         (string part : splited) {             system.out.println(part);         }     } } catch (ioexception e) {     system.out.println("there problem: " + e);     e.printstacktrace(); } {     try {         in.close();     } catch (exception e) {     } } 

also, don't forget, if open it, musty close ;)

you might want take little more time going through basic i/o ;)
