New to Java

I'm new to Java (only a few weeks under my belt) and struggling with an application. The project is to write an app that inputs 5 numbers between 10 and 100, not allowing duplicates, and displaying each correct number entered, using the smallest possible array to solve the problem. Output example:

Please enter a number: 45
Number stored.
45
Please enter a number: 54
Number stored. 45 54
Please enter a number: 33
Number stored.
45 54 33

etc.

I've been working on this project for days, re-read the book chapter multiple times (unfortunately, the book doesn't have this type of problem as an example to steer you in the relatively general direction) and am proud that I've gotten this far. My problems are 1) I can only get one item number to input rather than a running list of the 5 values, 2) I can't figure out how to check for duplicate numbers. Any help is appreciated.

My code is as follows:

import java.util.Scanner; // program uses class Scanner

public class Array
{

	public static void main( String args[] )
	{
      // create Scanner to obtain input from command window
	     Scanner input = new Scanner( System.in);

      // declare variables
         int array[] = new int[ 5 ]; // declare array named array
         int inputNumbers = 0; // numbers entered


      while( inputNumbers < array.length )
      {

	     // prompt for user to input a number
	       System.out.print( "Please enter a number: " );
             	int numberInput = input.nextInt();

	     // validate the input
		   if (numberInput >=10 && numberInput <=100)
     	   	 System.out.println("Number stored.");
			  else
     	         System.out.println("Invalid number.  Please enter a number within range.");

		// checks to see if this number already exists
                boolean number = false;

		// display array values
		for ( int counter = 0; counter < array.length; counter++ )
		   array[ counter ] = numberInput;

		// display array values
		   System.out.printf( "%d\n", array[ inputNumbers ] );

               // increment number of entered numbers
 		  inputNumbers++;
	    }
     }

} // end close Array
