Use nested for loops statements to draw empty boxes of any character (user input). The boxes have the same number of rows and columns (user input - valid range: 5 to 21). Test for errors in input (including type). Use the sample output to fully understand the program requirements.

How do I fix this?

import java.util.Scanner; public class Nested { 5 public static void main(String[] args) { Scanner input = new Scanner(System.in); //declare variables char ans = 'N'; int row = 0; char value = 'k'; System.out.println("Do you want to start put (Y/N)"); ans = input.next().charAt(0); if(ans == 'n' || ans == 'N'); System.exit(0); } else { System.out.println("How many chars/last row?"); while (!input.hasNextInt()) { System.out.println("ERROR! Valid range 5 - 21. How many chars/last row?"); input.next(); } Row = input.nextInt(); while (Row 21) { System.out.println("Not an integer! Try again! How many chars/last row?"); Row = input.nextInt(); } System.out.println("What character?"); val = input.next().charAt(0); for (int i = 1; i 21) { System.out.println("Not an integer! Try again! How many chars/last row?"); Row = input.nextInt(); } System.out.println("What character?"); val = input.next().charAt(0); for (int i = 1; i
