Question

The goal of this problem is to practice using appropriate branching statements. You will add to the main method to take in user input and output a message based on the input. This program emulates a detective questioning an eye-witness of a murder. The detective has three suspects each with a potential murder weapon. Based on the eye-witness's user input, the detective will reach a conclusion about the murderer and the murder weapon. If the witness input is "Amos" the detective will output "It was Amos with the candlestick!" If the witness input is "Kevin", the detective will output "It was Kevin with the revolver!" If the witness input is "Juan", the detective will will output "It was Juan with the lead pipe!" Otherwise, the detective will output "We're not sure who that is. We need to investigate further." Your program should also handle situations where the witness input does not use proper-case. Hint: look at the toUpperCase() or equalsignoreCase() method for Strings. Example input: amos Example output: It was Amos with the candlestick!

Answer:

Here is the code:

Explanation:

if else if else blocks are used . witness input is taken from the user using next() function from Scanner and is stored in a String variable. After that, equalsIgnoreCase function is used to compare the strings with the witness input.

import java.util.Scanner;
public class Clue
{
   public static void main(String[] args) {
       Scanner scnr = new Scanner(System.in);
       System.out.println("Who was the murderer?");
      
       String witness_input = scnr.next();
      
       if(witness_input.equalsIgnoreCase("Amos"))
       {
       System.out.println("It was Amos with the candlestick!");
       }
       else if(witness_input.equalsIgnoreCase("Kevin"))
       {
       System.out.println("It was Kevin with the revolver!");
       }
       else if(witness_input.equalsIgnoreCase("Juan"))
       {
       System.out.println("It was Juan with the lead pipe!");
       }
       else
       {
       System.out.println("We're not sure who that is. We need to investigate further.");
       }
   }
}

output:

Who was the murderer? amos It was Amos with the candlestick! ... Program finished with exit code 0 Press ENTER to exit console.
