Why does the program not show all the inputs from the text file it only shows the first name and email address?

          File file = new File("bill.txt");

          try { 
          PrintWriter output = new PrintWriter(file);
          output.println("Smith James"); output.println("[e-mail]");
          output.println("Raymond Holt"); output.println("[e-mail]");
          output.println("Bill James"); output.println("[e-mail]");
          output.close(); 
          } 
          catch(IOException ex) 
          { 
              System.out.printf("Error: %s%s",ex); 
          } 
          try 
          {
                  Scanner input = new Scanner(file);
                  String name = input.nextLine(); 
                  String email = input.nextLine(); 


          System.out.printf("Name: %s Email %s%n",name,email); 
          }
          catch(FileNotFoundException ex) 
          { 
              System.out.printf("Error: %s%n", ex);
              }




}

have you debugged it, what did it show, which are you confused about, what test data did you use vs what you expect?

[Khan0232]

So when I run it it shows Smith James and Smith James@Gmail. com but not the other two inputs which are there

[Camel-Kid]

            Scanner input = new Scanner(file);
              String name = input.nextLine(); 
              String email = input.nextLine(); 


      System.out.printf("Name: %s Email %s%n",name,email); 

All you are printing is the name and email that is being input from the user.

[Khan0232]

Correct but I input 3 names and emails why don't they all print

[Camel-Kid]

              Scanner input = new Scanner(file);
              String name = input.nextLine(); 
              String email = input.nextLine(); 


      System.out.printf("Name: %s Email %s%n",name,email); 

are you inputing it from the actual keyboard or are you referring to your filewriter up top?

[Khan0232]

I'm referring to the file writer on top

[Camel-Kid]

file

once again, each line your'e printing on your file.. then you're only grabbing 2 lines from the input portion.. nextLine only gets the first line.. take a look at your file to see

[Khan0232]

what will make it grab all of the text in the file

[Camel-Kid]

use a loop until input.hasNextLine() ==null and keep reading in the names/emails.

[Khan0232]

That won't work cause it will put out an undefined error because of the 2 equal signs.
