QUESTION : Please tell mE what is done in this program in detail..

import java.util.*; class AirLineReservation { boolean seatchart[]; //An array of seatchart int economy,firstclass; //Count of economy and firstclass AirLineReservation() //Default constructor to initialize false to all { seatchart=new boolean[10]; for(int i=0;i<10;i++) seatchart[i]=false; economy=5; firstclass=0; } void bookEconomy() //method to book economy as true { if(economy<10) seatchart[economy++]=true; } void bookFirstClass() //method to book firstclass as true
