Writing Classes in AP Computer Science A

Incorrectly writing shorter and cleaner code but potentially introducing security vulnerabilities into program logic concerning data encapsulation..

Incorrectly simplifying reference chains causing unintentional side-effects particularly when dealing with multithreading or concurrent processing environments..

Incorrectly optimizing memory usage as this refers locally rather than calling externally defined attributes or methods possibly leading to inefficient resource management..

Incorrectly accesses enclosing class members resulting in unexpected behavior or bugs that may be difficult to trace back within complex code structures..

Assigning values within static context where no instance exists.

Calling a static method within another static method in the same class.

Differentiating between field names and parameters with identical names in constructors or methods.

Accessing fields or methods from unrelated classes.

Whenever private access modifiers are used for that instance variable

When there is no local variable with the same name as the instance variable

Only inside static methods where it cannot be used anyway

When calling another method from within your method

It helps one overloaded constructor invoke another, saving repeated initialization code.

It follows from one overloaded constructor exit immediately upon completion.

It forces garbage collection process to begin cleanup resources held by the object being constructed.

It generates compile-time errors due duplicate signatures among multiple constructors.

A reference to the current object

The value of the static variables within the class

An integer representing the object's memory address

A copy of all instance variables within the class

new

class

super

this

Any object other than the one in which the method was called.

The current instance within which the exception occurred.

A static method where the exception must be handled.

The superclass from which an exception is inherited.

Upon finding duplicate identifiers across different scopes i.e., local vs global namespaces, ‘the’.priority gives precedence based upon closeness proximity relative to where it is called from

Exception handling mechanism captures all errors occurring due to misuse/misplacement of ‘the’, thereby providing detailed feedback messages to users about their mistakes

When placed at beginning lines after opening curly brackets { }, ‘the’ ensures strict enforcement against inheritance rules denying subclasses rights to modify parent members

When invoked inside any subclass, ‘the’ directs control flow toward superclass’s corresponding member function definitions

O(N)

O(N log N)

O(N^2)

O(1)

It allows distinguishing between member variables and parameters with identical names.

It rethrows the same exception to another constructor overload for handling.

It automatically resolves any exceptions without additional code.

It associates the caught exception with global variables rather than local ones.
