Answer:
public class ANot {
public static void main(String[] args) {
System.out.println("Enter a char");
Scanner in = new Scanner(System.in);
char letterStart = in.next().charAt(0);
char nextCha = (char)(letterStart+1);
System.out.print(letterStart);
System.out.println(nextCha);
}
}
Explanation:
The main logic here is understanding that characters in Java are stored as ASCII numbers and as such some mathematic operations can be carried out on them. So we add 1 to the value of the entered character to get the character next to it, the opposite is also possible (Subtracting 1 to get the value before it)
Note also that in reading a character using the scanner class Java does not support the nextChar like it does for other primitive data types so we use the method charAt(). To obtain the character at a particular index.
