Read a $3-$character string from input into variable inString. Declare a Boolean variable containsAlpha and assign containsAlpha with true if inString contains an alphabetic character. Otherwise, assign containsAlpha with false.

Ex: If the input is zrg$,$ then containsAlpha is assigned with true, so the output is:

string is valid

Ex: If the input is & & $,$&$,$ then containsAlpha is assigned with false, so the output is:

String is not valid

Note: Use inString $=$ scnr$.$nextLine $()$ to read the entire line from input into inString.

import java.util.Scanner;

public class StringChecker $\{$

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

Scanner scnr $=$ new Scanner$($

System.in$)$;

String instring;

if $($containsAlpha$)\{$

$\}$

System.out.println$("$String is valid"$)$;

else $\{$

$\}$

System.out.println$("$String is not valid"$)$;
