Thread: i feel like a retard! Java noob

I´ve been learning java for a week, 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.

 
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++;
		}
		}
	}
}

Learning for only a week?
Thinking about programming in your spare time?
Curious enough to write a program just because you think you can?
So you actually do it...and in only 3 hours...
Does it work?
..If every beginner had your problems, schools would not exist..


I entered 0, and nothing was printed as I expect.
I was not happy with entering 1, I expected to see a single zero printed instead of nothing
Other + integers worked as expected.

Pat yourself on the back for a job well done.

Perhaps troubleshoot and fix the code so that entering 1 will cause it to print a square of size 1 (a single zero).
Try to write the program a different way but make it do the same thing.
Modify the code so you can enter any letter of choice to build the square from instead of always 0.

Patience is virtue my friend ahha
