Getters
lAttributes
of objects should never be accessed within an
object simply by referring to them:
Quantity x = new Quantity(É);
É
System.out.println(x.Num);
Quantity x = new Quantity(É);
É
System.out.println(x.Num);
lexcept possibly for debugging purposes.
lInstead,
use a getter method:
int getNum()
{
return Num;
}
...
System.out.println(x.getNum());
int getNum()
{
return Num;
}
...
System.out.println(x.getNum());
