In Java, $($Display pyramid upside down$)$ Write a program that prompts the user to enter an integer from $1$ to $15$ and displays a pyramid. My code isn't working and was wondering if someone could fix it:

package chapter$5$ex$3$;

import java.util.Scanner;

public class Chapter$5$Ex$3\{$

public static void main$($String$[]$ args$)\{$

Scanner input $=$ new Scanner$($System$.$in$)$;

System.out.print$("$Enter a number between $1-15$: $")$;

int numberOfLines $=$ input.nextInt$()$;

int i;

int j;

int k;

int x;

boolean b $=$ true;

for $($int rows $=1$; rows $<=$ numberOfLines; rows$++)\{$

for $($i $=$ x; i $>0$; i$--)\{$

for $($j $=$ i; j $>0$; j$--)\{$

for $($k $=0$; k $<(($x $-$ i$))$ && b; k$++)\{$

System.out.print$("")$;

$\}$

if $($x $>9$ && j $>8$ && b$)\{$

for $($k $=0$; k $<($x $-$ j$)$; k$++)\{$

System.out.print$("")$;

$\}$

$\}$

if $($x $>9$ && j $<9$ && b$)\{$

for $($k $=0$; k $<$ x $-9$; k$++)\{$

System.out.print$("")$;

$\}$

$\}$

System.out.print$($j $+"")$;

b $=$ false;

$\}$

for $($j $=2$; j $<($i $+1)$; j$++)\{$

System.out.print$($j $+"")$;

$\}$

System.out.println$()$;

b $=$ true;

$\}$

$\}$

$\}$
