Thread: Java phonebook help

so i'm in process of making phonebook application , i'm looking guidance.

far application takes input .txt file , prints out first 3 lines.

asks user input information, , allows user search term inside entertered information.

want code read in .txt file, , ask user want search for, reply line information on, rest of information.

e.g. "enter search term" - 'ubuntu'

'ubuntu' found on line 22 , phone number 0123456789

suggestions?

(code below)

code:

import java.util.scanner;  import java.io.file;  import java.io.ioexception;   import java.io.bufferedwriter;  import java.io.bufferedreader;  import java.io.filereader;    import java.io.inputstreamreader;  import java.util.regex.matcher;  import java.util.regex.pattern;             class blondie          {                  public static void main(string args[])               throws ioexception                 {              scanner fileinput = new scanner(new file("/users/josh/dropbox/jubilee healthcare/java app/code/phone.txt"));                                   system.out.println("");                  system.out.print("name:               ");                             system.out.println(fileinput.nextline());                               system.out.print("telephone number:   ");                  system.out.println(fileinput.nextline());                  system.out.print("address:             ");                  system.out.print(fileinput.nextline());                  system.out.println("");                  system.out.println("");                             bufferedreader fileoutput = new bufferedreader(new inputstreamreader(system.in));                system.out.println("enter information: ");                                try      {                               string text = fileoutput.readline();                  system.out.println("enter word search for: ");                  string word = fileoutput.readline();                  string[] textsplit = text.split(" ");                                                     for(string str:textsplit)      {                   if(str.equalsignorecase(word))                  system.out.println(word + " can found here - " + text);                                      else                                      system.out.println("sorry can't find that, mind trying again?");                            }         }              catch(ioexception e)      {              e.printstacktrace();           }          }             }

how considering classes this?

maybe have phone book class called phonebook, contained arraylist of contact classes.

create phonebook when start application passing name of txt file constructor:

myphonebook = new phonebook("mytxtfile.txt");

constructor read text file , create number of contact classes added arraylist. (try use arraylist rather using array).

phonebook class have method called lookup(string value) when called looked contact class in list had appropriate values.
