I was wondering how it can just access BookLending in the Java example code? Wouldn’t it have to pass a reference to BookLending in the method?
public boolean checkout(String memberId) {
if(bookItem.getIsReferenceOnly()) {
ShowError("This book is Reference only and can't be issued");
return false;
}
if(!BookLending.lendBook(this.getBarCode(), memberId)){
return false;
}
...
