gel class (object) how, and where, to get to, and to execute, the
public void
.isRight() {...}
method structure, which will pass over the
private boolean
right
variable encapsulated in an InvinciBagel object. This is included here as a
demonstration of the Java OOP concept of “encapsulation.”
Your new .update() method body will use the same six lines of Java code, modified
to call the
.is()
methods on the inside of the
if(condition=true)
evaluation portion of
your existing conditional if structure. The new Java code, which is also shown in
Fig-

if(invinciBagel.
isLeft()

Insert the invinciBagel.is() method calls inside of the if statements, where the boolean variables used to
be
As you can see in

, the code is error-free, and you now have an .up-
date() method that accesses the Boolean variables from your InvinciBagel.java class
without having to use any import static statements to do so.
