Question

Write a program in Java to input a letter. If it is an uppercase letter then

encode it by next 5th letter, otherwise encode it with 3rd previous letter in the

ASCII table.​

Answer 1

The program is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

char chr;

System.out.print("Input Character: ");

chr = input.next().charAt(0);

if(Character.isUpperCase(chr) == true){ chr+=5; }

else{ chr-=3; }

System.out.println("Encode Character: "+chr);

}

}

Step-by-step explanation:

This declares the character

char chr;

This prompts for input

System.out.print("Input Character: ");

This gets the input from the user

chr = input.next().charAt(0);

This checks for uppercase; if true, it is encoded by the next 5th

if(Character.isUpperCase(chr) == true){ chr+=5; }

If lowercase, it is encoded by the previous 3rd

else{ chr-=3; }

This prints the encoded character

System.out.println("Encode Character: "+chr);
