Code wont compile and gives me and error on "while(answer.equalsIgnoreCase("y"));":

import java.util.Scanner;

public class TriangleofSquares {

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

String answer;

do {

System.out.print("Enter Number between 1 and 9 : ");

int n = input.nextInt();

while(n < 0 || n >=9)

{

System.out.print("Please enter a valid value between 1 and 9 :");

n = input.nextInt();

}

System.out.println("Here Is the Result");

for(int i=0;i

{

for(int j=0;j<=n*2-(i+i);j++)

{

System.out.print(" ");

}

for(int l=i+1;l>0;l--)

{

int r=l*l;

System.out.print(r+" ");

}

System.out.println(" ");

System.out.print("Run again? Enter y or n");

answer = input.next();

}

}

while(answer.equalsIgnoreCase("y"));

}

}

If a user enters "4" then this should be the output

 1 4 1 9 4 1 16 9 4 1 

Run again? Enter y or n
