There are many ways in doing this.

I used the substring method and a for loop to do it. I know maybe this is not the best way but you can try it. :)

i really am new... *sigh* i tried to make one earlier.. and it went like this...
public class prelimActivity3 {

 public static void main (String args[]) {

    	String inarray=JOptionPane.showInputDialog ("Enter number array: ");

    	int a=Integer.parseInt (inarray);

    	int [] b={a};


	System.out.println (b[]);

    }



}

it had an error of .class expected...
at the System.out part...
i'm really really new... and i don't know what to do.... thanks for the help...

I amended your code a bit.

public static void main (String args[]) {
        int counter = 0;
        int[] b;
        b = new int[5];
        while (counter < 5){
            String inarray = JOptionPane.showInputDialog ("Enter 5 numbers: ");
            int a = Integer.parseInt(inarray);
            b[counter] = a;
            counter++;
        }

        for(int i=0; i<b.length; i++){
            System.out.print(b[i] + " ");
        }

    }

Actually I consider myself a beginner in java and I am not really good in it also. Hopefully it helps.

Regards.
