Can someone look over this java program please?

Its suppose to output a triangle depending on the users input
ex

input-3
output
3
33
333
33
3
input-7
output
7
77
777
7777
77777
777777
7777777
777777
77777
7777
777
77
7

I know that right now it won't really work for numbers over 9


here it is



import java.util.Scanner;

public class TriangleOfDigits
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
int rows = input.nextInt();
//outer loop says how many lines
//*n by 2 and - 1 (how many lines needed

for (int rowNumber = 1; rowNumber <= rows; rowNumber++);
{
//inner loop says how many things on this line
for(int colNum = 1; colNum <= rowNumber; colNum++);

{

//print out thing
System.out.print(rows);
}

System.out.println();
}

for (int rowNumber = 1; rowNumber <= rows; rowNumber++);
{
//inner loop says how many things on this line
for(int colNum = rows; colNum > rowNumber; colNum--);
{
//print out thing
System.out.print(rows);
}

}



System.out.println();
}
}




These are the error messages Im getting


TriangleOfDigits.java:16: cannot find symbol
symbol : variable rowNumber
location: class TriangleOfDigits
for(int colNum = 1; colNum <= rowNumber; colNum++);
^
TriangleOfDigits.java:31: cannot find symbol
symbol : variable rowNumber
location: class TriangleOfDigits
for(int colNum = rows; colNum > rowNumber; colNum--);




Im not quite sure how to fix this

thanks in advance

You're for loops shouldn't have the ';' after the declaration. It should look like this.

Code:

---

    for (int i = 0; i < list.size(); i ++) {
          //your code here...
    }

---

Take the ';' off the for loops and see what you get.

@StormyWaters
thanks you very much! It works perfectly now.
