Solution

Java Class: without main method (as per requested):

class Concert{
private String name; //variable for band name
private int capacity; //variable for capacity
private int byPhone; //variable for no of tickets sold by phone
private int atVenue; //variable for no of tickets sold at vnue
private int phonePrice; //variable for phone price of ticket
private int venuePrice; //variable for venue price of ticket
  
// default constructor with default values
public Concert(){
this.setName(\"default name\");
       this.setCapacity(100);
       this.setByPhone(0);
       this.setAtVenue(0);
       this.setPhonePrice(10);
       this.setVenuePrice(8);
}
     
   // constructor with parameters
   public Concert(String bandName, int capacity, int phonePrice, int venuePrice){
this.setName(bandName);
       this.setCapacity(capacity);
       this.setPhonePrice(phonePrice);
       this.setVenuePrice(venuePrice);
}
     
      // constructor with parameters
   public Concert(String bandName, int capacity, int byPhone, int atVenue, int phonePrice, int venuePrice){

       this.setAtVenue(atVenue);
       this.setPhonePrice(phonePrice);
       this.setVenuePrice(venuePrice);
}
  
// setter & getter methods for variables
   public void setName(String name){
       this.name = name;

   public void setAtVenue(int atVenue){
       this.atVenue = atVenue;
   }
   public int getAtVenue(){
       return atVenue;
   }
     
   public void setPhonePrice(int phonePrice){
       this.phonePrice = phonePrice;

   public void setVenuePrice(int venuePrice){

   }
   public int getVenuePrice(){
       return venuePrice;
   }

// method to trace the no of tickets sold
   public int totalNumberOfTicketsSold(){
       return getByPhone() + getAtVenue();
   }
// method to track tickets remaining to sell  
   public int ticketsRemaining(){
       return getCapacity() - totalNumberOfTicketsSold();
   }
// method to track no of tickets bought at venue  
   public void buyTicketsAtVenue(int noOfTickets){
       this.setAtVenue(noOfTickets);
   }
//method to track no of tickets bought by phone
   public void buyTicketsByPhone(int noOfTickets){
       this.setByPhone(noOfTickets);
   }
//method to calculate the sale of tickets both by phone & at venue
   public int totalSales(){
       return (getByPhone() * getPhonePrice() )+ ( getAtVenue() * getVenuePrice());
   }
}
