Question

Read a 2-character string from input into variable inString. Declare a Boolean variable isValid and assign isValid with true if inString does not contain any lowercase letters. Otherwise, assign isValid with false.

Ex: If the input is FB, then isValid is assigned with true, so the output is:

Valid string

Ex: If the input is kv, then isValid is assigned with false, so the output is:

Invalid string

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;

/* Your code goes here */

if (isValid) {
System.out.println("Valid string");
}
else {
System.out.println("Invalid string");
}
}
}
