i feel like a retard! Java noob!

**javanab** · 11-09-2012, 01:46 AM

I´ve been learning java for a week, my first programming language ever and im loving it. Im 31y and learning it as a hobby, yesterday while on bed, couldnt sleep i tought to myself, it would be a good excercise if i made a program where i would input the side of a square, then make the square representation.

Anyway i tought i would do this like in 10m, i spent 3hours till i got it right, feel a complete retard and my motivation is damm low right now.

Java Code:

import java.util.Scanner;

public class quadrado {

	public static void main(String[] args) {

		
		Scanner input = new Scanner(System.in);
		int quadrado;
		System.out.println("Insert Square Size");
		quadrado = input.nextInt();
	
		int counter = 1;
		int total=1;
		
		
		while(counter<quadrado){
			
			counter++;	
			total++;
			
			
			System.out.print("O   ");
		

			
		if(counter==quadrado){
			
			System.out.println("O   ");
			if((total)==(Math.pow(quadrado, 2))){break;}
			
			counter=1;
			total++;
		}
		}
	}
}

Did you have a specific question, or looking for tips, or something?

was curious , on a elegant way to write the program with the same output.

Hmm. I won't give you any code, but I see two other approaches.

1) Have two strings: One with enough 0s to match the length of the side, and one with the same amount of spaces. Then write "0"+border+"0" before a for-loop, "0"+spaces+"0" in a for-loop, and then "0"+border+"0" again after the for-loop. Voila, a nice square.

2) Use a for-loop within another for-loop. The first for-loop would represent the Y and the second the X. If the values of X and Y say it's along the border, print a "0". Otherwise print a space.

I'm sure there are other approaches as well, but those two were the ones that popped into my head.

EDIT: That is, of course, if I understood your intention correctly. For instance, if a user enters 4, it should output:

slick mod -.-, was looking for a java forum but found this one is much more active!

there's nothing wrong with cross-posting, but please notify all forums if you do that out of consideration so that we don't waste time duplicating effort that has been performed elsewhere.
