Question

I am having a few problems with this build. First it is not all it will not load the main class. Second I need the user to input their choice of music and then I need the compiler to print selection. Can someone help me with this code? Please excuse me but I am totally new to programming.

public class music {

public static void music(String[] args) {

    System.out.println("What's your favorite kind music?: ");
    System.out.println("1. Country");
    System.out.println("2. Rock");
    System.out.println("3. Heavy Metal");
    System.out.println("4. Folk");

    try{
    BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));
    int s = Integer.parseInt(bufferRead.readLine());
        switch(s){
            case 1:
                System.out.println("Country");
                break;
            case 2:
                System.out.println("Rock");
                break;
            case 3:
                System.out.println("Heavy Metal");
                break;
            case 4:
                System.out.println("Folk");
                break;
            default:
                System.out.println("Country");
                break;
      }



}catch(IOException e){
        e.printStackTrace();
    }

Solution

The problem with the source as posted is that you do not have an entry point to your class (i.e. a method called main).

Suggestions

Since you mentioned you are also new to programming, I’ve taken the liberty to include some stylistic suggestions to make your code simpler and easier to read (IMO):

import static java.lang.System.in;
import static java.lang.System.out;

import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Map.Entry;
import java.util.Scanner;

public class Music {

    private static final String DEFAULT_MUSIC = "Country";

    public static void main(String[] args) {
        Map<Integer, String> musicOptions = new LinkedHashMap<Integer, String>();
        musicOptions.put(1, DEFAULT_MUSIC);
        musicOptions.put(2, "Rock");
        musicOptions.put(3, "Heavy Metal");
        musicOptions.put(4, "Folk");

        out.println("What's your favorite kind music?: ");
        for (Entry<Integer, String> option : musicOptions.entrySet()) {
            Integer choice = option.getKey();
            String music = option.getValue();

            out.printf("%d. %s\n", choice, music);
        }

        final int choice = new Scanner(in).nextInt();
        String music = musicOptions.get(choice);
        if (music == null) {
            music = DEFAULT_MUSIC;
        }

        out.println(music);
    }

}
