I know for a Command Promt I would use this line

Java Code:

System.out.println

What would I use for a GUI?

In GUI such as Swing you can use something like JLabel, JTextField, JTextArea, etc. It depends on how you design your GUI and the Swing components that you want to use.

So what you are saying is that this:

Java Code:

System.out.print("This is the same");

Would produce the same output as this:

Java Code:

JOptionPane.showMessageDialog(null, "This is the same");

I am guessing not...because I switched all of the lines in my code to mirror the changes below, and it is still printing in a cmd window even tho there is NO code that says to print in a command window!!!???

Show your code so we can see it for ourselves.

Java Code:

	public static void main(String args[]){
    	 int n,i,j,k;

        String rowcountNum;
        int rowcount;
        rowcountNum = JOptionPane.showInputDialog("Enter Number Please");

        //convert numbers from String to type in
        rowcount = Integer.parseInt(rowcountNum);
        n=rowcount;
    

      //System.out.println(n);
	  JOptionPane.showMessageDialog(null, n);

      //System.out.println();
	  JOptionPane.showMessageDialog();

     for (i = 1; i <= n/2; i++){

     	for (k = n; k > i; k--)
     	JOptionPane.showMessageDialog(null, " ");
		//System.out.print(" ");

     	for (j =1; j <= i; j++)
		JOptionPane.showMessageDialog(null, "*" + " ");
         //System.out.print("*" + " ");

	   JOptionPane.showMessageDialog();
       //System.out.println();

     	}

     for (i = (n/2)+1; i > 0; i--){

     	for (k = n; k > i; k--)
     	  JOptionPane.showMessageDialog(null, " ");
		  //System.out.print(" ");

     	for (j =1; j <= i; j++)
         JOptionPane.showMessageDialog(null, "*" + " ");
		 //System.out.print("*" + " ");

       JOptionPane.showMessageDialog();
	   //System.out.println();

     	}
}
}
