FOR JAVA PLEASE: SIMPLE CODE: $1\mathrm{.}42$ LAB: Input and formatted output: Right$-$facing arrow

Given two input integers for an arrowhead and arrow body, print a right$-$facing arrow.

Ex: If the input is: $01$

the output is:

$1$

$11$

$00000111$

$000001111$

$00000111$

$11$

$1$import java.util.Scanner;

public class LabProgram $\{$

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

Scanner scnr $=$ new Scanner$($

System.in$)$;

int baseChar;

int headChar;

$/*$ Type your code here. $*/$

$\}$

$\}$

I used the following code: import java.util.Scanner;

public class LabProgram $\{$

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

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

System.out.print$("$Enter the base character: $")$;

char baseChar $=$ scanner.next$().$charAt$(0)$;

System.out.print$("$Enter the head character: $")$;

char headChar $=$ scanner.next$().$charAt$(0)$;

System.out.println$(""+$ headChar$)$;

System.out.println$(""+$ headChar $+$ headChar$)$;

for $($int i $=0$; i $<mtext\; id="EditorElement\_1141268"></mtext><mn\; id="EditorElement\_1141269">3</mn>$; i$++)\{$

for $($int j $=0$; j $<mtext\; id="EditorElement\_1141310"></mtext><mn\; id="EditorElement\_1141311">5</mn>$; j$++)\{$

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

$\}$

if $($i $==0||$ i $==2)\{$

System.out.println$($headChar $+""+$ headChar $+""+$ headChar$)$;

$\}$ else $\{$

System.out.println$($headChar $+""+$ headChar $+""+$ headChar $+""+$ headChar$)$;

$\}$

$\}$

System.out.println$(""+$ headChar $+""+$ headChar$)$;

System.out.println$(""+$ headChar$)$;

scanner.close$()$;

$\}$

$\}$

I received the following errors:LabProgram.java:$8$: error: cannot find symbol
