Question
Design a JAVA program that does all of the following:
• It allows the user to input a three letter word.
• It saves this word in an array / string.
• Then the program randomly picks a letter from the 26 letters of the alphabet and uses that letter to replace the first letter of the 3-letter word.
• The program checks if the randomly selected letter matches the first letter of the 3-letter word. If it does not, the program proceeds to the next letter and replaces it with a letter randomly selected from the 26 letters of the alphabet;
• If the randomly selected letter matches the first letter of the 3-letter word, the program randomly selects another letter and repeats that process until the randomly selected letter is different from the first letter of the 3-letter word.
****Please show a picture of your output and your code so there aren't any spacing issues.****
Explanation / Answer
RandomLetter.java
package org.students;
import java.util.Random;
import java.util.Scanner;
public class RandomLetter {
public static void main(String[] args) {
String str;char letter,symbol;
Scanner sc=new Scanner(System.in);
System.out.print("Enter a word::");
str=sc.next();
while(true)
{
letter=str.charAt(0);
Random r = new Random();
symbol = (char)(r.nextInt(26) + 'a');
String str1=str.substring(1);
str1=symbol+str1;
System.out.println(str1);
if(letter!=symbol)
continue;
//else if(letter==symbol)
// continue;
else
break;
}
}
}
