Question

Write program in JAVA with a method that returns an array. The method should accept as input a comma-delimited string with three values from a user. The array should store each value in a different element. Use Try..Catch error handling and print any failure messages, or print success from within method if execution is successful (see Chapter 13 in the text). Call the method from the main method of the program to demonstrate its functionality by looping through the array and printing the individual values. Submit your source code and screenshots of the application executing the application and the results in a single document.

import java.util.Scanner;

public class CommaSeparatedArray {

    public static String[] splitString(String s) {
        String[] words = s.split(",");
        for (int i = 0; i < words.length; i++) {
            words[i] = words[i].trim();
        }
        System.out.println("success");
        return words;
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter a command separated line: ");
        String[] words = splitString(in.nextLine());
        System.out.println("Words are");
        for (int i = 0; i < words.length; i++) {
            System.out.println(words[i]);
        }
        in.close();
    }
}
