java - My input only read three commands and does nothing with the ones it reads? -

-

i have write user interface takes in data command screen , uses access methods in linked list class. both in same file , node class written , compiles fine. if can me figure out why reads 3 commands, such dog, cat, p , says java.io.ioexception: stream closed. checked if adding spaces i.e. commanding dog cat, bird, p affected amount of lines read , didn't. exception same. tips appreciated.

public static void main(string[] args){     linkedlist link= new linkedlist();     int n=0;     system.out.println("type command\n");         try{         bufferedreader in=new bufferedreader(new inputstreamreader(system.in));             s=in.readline();             while(in.readline()!=null){                 s=in.readline();                 char first=s.charat(0);                 int space= s.indexof(" ");                 while(space<=n){                     if(first=='i'){                         string w=s.substring(space);                         link.insert(w);                     }                     if(first=='d'){                         string w=s.substring(space);                         link.delete(w);                         link.printlist();                     }                     if(first=='f'){                         string w=s.substring(space);                         link.find(w);                         link.printlist();                     }                     if(first== 'p'){                         link.printlist();                     }                     n++;                 }                 in.close();             }             }catch(exception e) {system.out.println("ack!: " + e);} }

stream closed error means trying write in after has been closed. format code this:

open in stream on line before try try {     processing here     ..... } catch(exception e) {    .... } {      close stream here }

the block run code needs run after running try/catch, put stream close there.
