Question

Write a Java class named StringProcess that prompts the user to enter two non-empty strings and report the followings: 1) The length of the two strings 2) The ASCII value of the first letter in the first string 3) The ASCII value of the last letter in the second string 4) Whether the second string is a substring of the first string.

Outputs: Your output should look similar as follows.

Please enter the first string: Carrot

Please enter the second string: Car

The ASCII value of the first letter in string carrot is: 67

The ASCII value of the last letter in string Car is: 114

The second string Car is a substring of the first string Carrot.

Answer 1

import java.util.Scanner;

public class StringProcess {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Please enter the first string: ");
        String s1 = in.nextLine();
        System.out.print("Please enter the second string: ");
        String s2 = in.nextLine();
        System.out.println("The ASCII value of the first letter in string " + s1 + " is: " + (int) s1.charAt(0));
        System.out.println("The ASCII value of the last letter in string " + s2 + " is: " + (int) s2.charAt(s2.length() - 1));
        if (s1.contains(s2)) {
            System.out.println("The second string " + s2 + " is a substring of the first string " + s1 + ".");
        } else {
            System.out.println("The second string " + s2 + " is not a substring of the first string " + s1 + ".");
        }
    }
}
