import java.io.FileWriter;
import java.io.IOException;
import java.util.List;

public class Hall {
    private String name;
    private String contact;
    private Double costPerDay;
    private String owner;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}
public static void writeHallDetails(List<Hall> halls) throws IOException{
