public class Q135Account {

Q135Account(int amount){
this.amount=amount;
}
public int getAmount() {
return amount;
}
void changeAmount(int x){
amount +=x;
}
public static void main(String[] args) {
Q135Account acct = new Q135Account((int)(Math.random()*1000));
// D acct.amount=0;
// G acct.changeAmount(-acct.amount);
// H acct.changeAmount(-acct.getAmount());
System.out.println(acct.getAmount());
