java - TextIO.getln() does not get input? -

i'm newbie in java. i'm reading book introduction programming using java v7 , found problem code this:

public class createprofile {    public static void main(string[] args) {     // todo auto-generated method stub         string name;         string email;         double salary;         string favcolor;          textio.putln("good afternoon! program create");         textio.putln("your profile file, if answer");         textio.putln("a few simple questions.");         textio.putln();          /* gather responses users. */           textio.put("what name?      ");         name = textio.getln();         textio.put("what email address?      ");         email = textio.getln();         textio.put("what salary income?      ");         salary = textio.getdouble();         textio.putln();         textio.put("what favorite color?     ");         favcolor = textio.getln();          /* write user's information file named profile.txt. */          textio.writefile("profile.txt"); //subsequent output goes file         textio.putln("name:     " + name);         textio.putln("email:    " + email);         textio.putln("favorite color:    " + favcolor);         textio.putf("yearly income:      %1.2f%n", salary);          /* print final message standard output. */          textio.writestandardoutput();         textio.putln("thank you. profile has been written profile.txt.");     } } 

the console not ask me input favorite color jump directly writing file process.

as when put favcolor input statement before salary, there seem no problem:

can please explain me why?

try removing textio.putln();

textio.put("what name?      "); name = textio.getln(); textio.put("what email address?      "); email = textio.getln(); textio.put("what salary income?      "); salary = textio.getdouble(); //textio.putln(); textio.put("what favorite color?     "); favcolor = textio.getln();
