#25259 — Nothing prints when I compile my code

Another Homework assignment for College Intro to Java course. I am having a disconnect with what the issue is. It compiles fine but does not print. Hints anyone?

Here is my code:

//*************************************************************************************************
// Author:	John Stephens			Date: September 7, 2013
// Class: COP 2551               Filename: Homesick.java
// Lab: Lab 1
// Programming Project PP2.3 on Page 109.
// Purpose:  This program prompts and reads a person's name, college, and petname into a paragraph
//*************************************************************************************************

import java.util.Scanner;

public class Homesick
{
   //----------------------------------------------------------------------------------------------
   // Reads a character string from the user and prints it.
   //----------------------------------------------------------------------------------------------
   public static void main (String[] args)
   {
    String name, college, petname;
    int age;
    Scanner scan = new Scanner (System.in);
    String Name = scan.nextLine();
     
    System.out.println ("Johnny");
    name = scan.nextLine();
    
    System.out.println ("41");
    age = scan.nextInt();
    scan.nextLine();
                
    System.out.println ("FSCJ");
    college = scan.nextLine();
               
    System.out.println ("Sagwa");
    petname = scan.nextLine();
            
    System.out.println ( "Hello, my name is " + name + " and I am " + age + " years " +
                         "old. I'm enjoying my time at, " + college + " though " +
                         "I miss my pet " + petname + " very much!" );
   }
}

It's because you didn't tell it to print anything.  Look at the code, 
you read the input (call 'nextLine' on the Scanner) before you print 
anything.  I'd suggest you add a prompt before each use of a scanner 
method to give you a hint when the scanner is waiting for input.

Here's an example:

 > {

 >      String name, college, petname;
 >      int age;
 >      Scanner scan = new Scanner (System.in);
        System.out.println( "Enter your name:" );   // add this
 >      String Name = scan.nextLine();
 >
 >      System.out.println ("Johnny");


Then you will see some output before the program waits.  Add an 
appropriate println before each use of a scanner method and the program 
will be easier to use.

see http://mindprod.com/jgloss/helloworld.html
for the usual things that go wrong with your first program.

Try adding a print at the top so you can at least make sure you
program is starting.

Your prompts look odd.  You should be prompting with field names, not
the data.
