Nothing prints when I compile my code

[John Stephens]

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:

import java.util.Scanner;

{

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:

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);

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.

Thank you!

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.
