Java Programing

Write a program called reverseProg.  

This program will do the following

1. Asks the user to input a string, it reads the string and does the followings
   1. Prints the string in reverse order.
   2. Displays the characters that are in position 7^th, 8^th and 9^th of this string
   3. Displays the length of the string
   4. Displays the string in all UPPER CASE

Wilmington University spelled backward is: ytsirevinU notgnimliW

The 7^th character in the string is: T

The 8^th character in the string is: O

The 9^th character in the string is: N

Length of the string is: 21

Answer 1

import java.util.Scanner;

public class reverseProg {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter a string: ");
        String s = in.nextLine();
        String rev = "";
        for (int i = 0; i < s.length(); i++) {
            rev = s.charAt(i) + rev;
        }
        System.out.println("String Entered is: " + s);
        System.out.println(s + " spelled backward is: " + rev);
        System.out.println("The 7th character in the string is: " + Character.toUpperCase(s.charAt(7)));
        System.out.println("The 8th character in the string is: " + Character.toUpperCase(s.charAt(8)));
        System.out.println("The 9th character in the string is: " + Character.toUpperCase(s.charAt(9)));
        System.out.println("Length of the string is: " + s.length());
    }
}
