in Java please.

What's wrong with my code?

import java.util.Arrays;

import java.util.Scanner;

public class LabProgram $\{$

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

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

char$[]$ chars $=$ new char$[3]$;

for $($int i $=0$; i $<mtext\; id="EditorElement\_122302"></mtext><mn\; id="EditorElement\_122303">3</mn>$; i$++)\{$

chars$[$i$]=$ scnr$.$next$().$charAt$(0)$;

$\}$

Arrays.sort$($chars$)$;

for $($char c : chars$)\{$

System.out.printf$($c $+"")$;

$\}$

System.out.println$()$;

scnr$.$close$()$;

$\}$

$\}$
