JAVA PROGrAMMING:

Using the attached program as a starter, make the following enhancements:

move the user prompt strings to a properties file

create a corresponding properties file for another language/region

query the current system Locale and display it

display the menu from your properties file

change the JVM's Locale

display the menu from your properties file (again)

import java.io.FileNotFoundException;
import java.io.IOException;
import java.net.URISyntaxException;
import java.util.Scanner;

public class MenuFromProperties {

   private static final String[] TOP_MENU = { "List Library", "Sort Library By Composer", "Sort Library By Genre",
           "Sort Library by Duration", "Play Playlist", "Create Playlist", "Exit" };

   public static void main(String[] args) throws InterruptedException, URISyntaxException, FileNotFoundException,
           IOException, ClassNotFoundException {

       Scanner kybd = new Scanner(System.in);

       int userChoice = -1;

       userChoice = Utils.userChoose(kybd, TOP_MENU);
   }

}

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Utils {

   public static int userChoose(Scanner kybd, String[] choices) {
       int choice = -1;
       System.out.println("Make a Selection: ");
       for (int i = 0; i < choices.length; i++) {
           System.out.println(" [" + i + "] " + choices[i]);
       }
       choice = kybd.nextInt();
       return choice;
   }

   public static int userChoose(Scanner kybd, List<String> choices) {
       int choice = -1;
       System.out.println("Make a Selection: ");
       for (int i = 0; i < choices.size(); i++) {
           System.out.println(" [" + i + "] " + choices.get(i));
       }
       choice = kybd.nextInt();
       return choice;
   }
}

Explanation / Answer

import java.io.FileNotFoundException;
import java.io.IOException;
import java.net.URISyntaxException;
import java.util.Scanner;
public class MenuFromProperties {

Properties props = new Properties();
       InputStream is = null;
       try {
File f = new File("menu.properties");
       is = new FileInputStream( f );
}
catch ( Exception e ) { is = null; }

       try {
if ( is == null ) {
is = getClass().getResourceAsStream("menu.properties");
}

// Try loading properties from the file (if found)
props.load( is );
}
catch ( Exception e ) { }
  
   private static final String[] TOP_MENU = props.getProperty("TOP_MENU");        // We set this priorly
//private static final String[] TOP_MENU = { "List Library", "Sort Library By Composer", "Sort Library By Genre",
"Sort Library by Duration", "Play Playlist", "Create Playlist", "Exit" };
public static void main(String[] args) throws InterruptedException, URISyntaxException, FileNotFoundException,
IOException, ClassNotFoundException {
       try {
File f = new File("userChoice.properties");
OutputStream out = new FileOutputStream( f );
}
catch (Exception e ) {
e.printStackTrace();
}
Scanner kybd = new Scanner(System.in);
int userChoice = -1;
userChoice = Utils.userChoose(kybd, TOP_MENU,out,props);
}
}
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class Utils {
public static int userChoose(Scanner kybd, String[] choices,OutputStream out,Properties props) {
int choice = -1;
System.out.println("Make a Selection: ");
for (int i = 0; i < choices.length; i++) {
System.out.println(" [" + i + "] " + choices[i]);
}
choice = kybd.nextInt();
       props.store(out, choice);     
return choice;
}
}
