أهلًا بك،
الحل بالترتيب يمكن أن يكون كالتالي:
this.address=adr;
this.address=adr;
return this.address;
int index=0; int count=0;
while(Collection[index] != null)
{
count++;
index++;
}
Collection[count]== new Book(bookObject.bookTitle);
Collection[count].borrowed=bookObject.borrowed;
for (int i = 0; i < Collection.length; i++)
System.out.println("Book "+ i+1+ " name is:" + Collection[i].bookTitle);
return this.Collection;
/////////
this.bookTitle=bookTitle;
this.borrowed=true;
this.borrowed=false;
if(this.borrowed)return true; else return false;
return this.bookTitle;
this.bookTitle=bookTitle;
