Read a 3-character string from input into variable inString. Declare a Boolean variable isValid and assign isValid with true if inString does not contain any digits. Otherwise, assign isValid with false.
Ex: If the input is jxy, then isValid is assigned with true, so the output is:
string is valid
Ex: If the input is s9q, then isValid 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 StringModification {
public static void main(String[] args){
Scanner scnr = new Scanner(
System.in);
String instring;
Y** Your code goes here */
if (isvalid){
System.out.println("String is valid");
}
else {
System.out.println("String is not valid");
}
}
}
