Answer 1

// TestCode.java
public class TestCode {
    public static void main(String[] args) {
        String s = "IT 206 is a GREAT class!";

        if(s.charAt(7)>='0' && s.charAt(7)<='9'){
            System.out.println("Character is a digit!");
        }
        else{
            System.out.println("Character is not a digit!");
        }
    }
}

String s = "IT 206 is a GREAT class!";

if(s.charAt(7)>='0' && s.charAt(7)<='9'){
    System.out.println("Character is a digit!");
}
else{
    System.out.println("Character is not a digit!");
}
