I'm taking a java class and having trouble figuring out why this code doesn't compile correctly. The code is straight from the book so I think I might be doing something wrong? Any help would be appreciated.

When you run a Java console program, you have to have at least a class Main inside of your program for it to run. So, what I did was renamed the main function inside of your Clock class to be a clock function, and then inside of a new public class Main made the main function that runs with every program and called Clock.clock(); to run the clock program.

Here is the repl code: https://repl.it/@heyitsmarcus/The-Clock-Program-1

import java.util.*; public class Main { public static void main(String[] arguments) { //run the clock program automatically upon execution Clock.clock(); } } class Clock { public static void clock() { // get current time and date Calendar now = Calendar.getInstance(); int hour = now.get(Calendar.HOUR_OF_DAY); int minute = now.get(Calendar.MINUTE); int month = now.get(Calendar.MONTH) + 1; int day = now.get(Calendar.DAY_OF_MONTH); int year = now.get(Calendar.YEAR); // display greeting if (hour < 12) { System.out.println("Good morning.\n"); } else if (hour < 17) { System.out.println("Good afternoon.\n"); } else { System.out.println("Good evening.\n"); } // begin time message by showing the minutes System.out.print("It's"); if (minute != 0) { System.out.print(" " + minute + " "); System.out.print((minute != 1) ? "minutes" : "minute"); System.out.print(" past"); } // display the hour System.out.print(" "); System.out.print((hour > 12) ? (hour - 12) : hour); System.out.print(" o'clock on "); // display the name of the month switch (month) { case 1: System.out.print("January"); break; case 2: System.out.print("February"); break; case 3: System.out.print("March"); break; case 4: System.out.print("April"); break; case 5: System.out.print("May"); break; case 6: System.out.print("June"); break; case 7: System.out.print("July"); break; case 8: System.out.print("August"); break; case 9: System.out.print("September"); break; case 10: System.out.print("October"); break; case 11: System.out.print("November"); break; case 12: System.out.print("December"); } // display the date and year System.out.println(" " + day + ", " + year + "."); } }
