Using Objects in AP Computer Science A

Composition leads to tighter inter-class relationships enhancing both reusability and reliability during updates.

Inheritance provides stronger coupling between superclasses and subclasses, simplifying feature addition processes significantly.

Composition allows new functionality through additional objects without altering existing hierarchy or risking impact on inherited behavior.

Utilizing inheritance enforces consistent implementation details throughout all derived classes making feature integration seamless.

while loop

do-while loop

if-else chain

for loop

Automatic resizing when more space is needed.

Runtime errors when adding new elements.

Wasted memory space due to unused indices.

Improved performance due to pre-allocation.

Individual unrelated concrete classes for each product category containing duplicate basic attributes such as price and description.

One generic product class providing all possible properties across categories using boolean flags to activate relevant traits per instance.

Abstract classes defining core properties with subclass extensions for unique category traits like electronics having additional warranty details.

Multiple interfaces representing various product traits used in conjunction by each category-specific subclass to implement required behaviors.

The program immediately halts without any chance for recovery.

The exception gets logged automatically by Java's built-in logger.

The method terminates and the exception propagates up to the caller.

The compiler generates additional code to wrap the exception silently.

Utilize Java's Fork/Join Framework entirely replacing quicksort logic.

Divide array into segments parallelly quicksort each then merge them sequentially.

Apply synchronized blocks liberally throughout current quicksort code.

Introduce wait()/notify() mechanisms around pivot selection logic.

The array is sorted in ascending order before finding the maximum.

The return statement is outside of the loop that iterates through the array elements.

An ArrayIndexOutOfBoundsException is thrown during execution.

The loop initializes the max variable with the first element but never updates it.

The current object whose method or constructor is being invoked.

A superclass from which the current class inherits methods or fields.

The class that contains the method where 'this' keyword appears.

A static variable shared among all instances of a class.
