public class RMS {

  
public static void main(String[] args) {
System.out.println("Welcome to Restorent Employee Management System!");
while(true){
System.out.println("1. Enter Owner Menu");
System.out.println("2. Show Emplyoee work Hours");
System.out.println("3. Exit");
  
Owner o = new Owner();
Scanner sc = new Scanner(System.in);
int ch = sc.nextInt();
switch(ch){
case 1:
o.setWorkHours();
break;
case 2:

break;
case 3: return;
}
}
  
}
  
}

Owner Class:
