Question

Write an application that uses an Array to store 10messages of type String. You will store this Array with 10 messages of your choosing. For example, a message could be “I love Java the programming language!” or another message could be “I love Java the drink!” You may initialize your Array with the messages or have the user enter the messages. The choice is yours. Your Java code will contain a method called shoutOutCannedMessage() that will loop through the Array to iterate through your entire list and display each message and allow the user to select one. The shoutOutCannedMessage() will return the selected message String

Explanation / Answer

/**The java program MessageProgram that prompts
* to enter the user choice of an array of messages
* and then the method shoutOutCannedMessage returns
* the user selected choice to the main method*/
//MessageProgram.java
import java.util.Scanner;
public class MessageProgram
{  
  
   //create an array of messages
   private static String messages[]=
                   {"I Love java",
                   "I love Java the programming language!",
                   "I love Java the drink!",
                   "Java is OOP",
                   "Java-James Gosling",
                   "Java virtual Machine",
                   "Fun to program-java",
                   "Platform independent-java",
                   "Open source-java",
                   "Have a smart programming-java"
                   };
  
  
   public static void main(String[] args)
   {
       //call the method shoutOutCannedMessage
       String selectedMessage=shoutOutCannedMessage();
       //print the user selected choice
       System.out.println("User selected choice is "+selectedMessage);
      
   }

   /**The method shoutOutCannedMessage that print the array of string
   * messages and prompt for user choice and returns selected
   * choice fromt the method.*/
   private static String shoutOutCannedMessage()
   {
       //Create a scanner class
       Scanner scanner=new Scanner(System.in);
       //integer variable of choice
       int choice;
      
       //iterate over the messages array and print the values
       for (int index = 0; index < messages.length; index++)
       {
           System.out.println((index+1)+")"+messages[index]);
       }
      
       System.out.println("Enter your choice .");
       //prompt for user choice
       choice=scanner.nextInt();
      
       //return choice
       return messages[choice-1];
   }

}
