Code Handout to accompany the Final Exam CSCI 455 [S18 Bono]

[Java] Select Java Scanner and File constructors:

public File(String pathname) Creates File object from given pathname. Does not open any file on disk.

public Scanner(File source) throws FileNotFoundException

Constructs a new Scanner that produces values scanned from the specified file.

FileNotFoundException (a checked exception) is thrown if source file is not found on disk.

[Java] Set<ElmtType> Interface

The classes that implement this interface are: TreeSet and HashSet.

Selected methods:

boolean contains(ElmtType elmt) Returns true iff elmt is in the set

int size() Returns number of elements in the set

boolean add(ElmtType elmt) Ensures that elmt is in the set.

Returns true iff the set changed as a result of this call

boolean remove(ElmtType elmt) Removes elmt from the set.

Returns true iff the set changed as a result of this call

boolean isEmpty() Returns true iff the set contains no elements.

Iterator<ElmtType> iterator() Returns an iterator over the elements in the set.

[Java] Iterator<ElmtType> Interface

Selected methods:

boolean hasNext()

Returns true iff the iteration has more elements.

ElmtType next()

Returns the next element in the iteration. Each successive call returns a different element in the

underlying collection.

[Java] MazeCoord Class

Selected methods:

MazeCoord(int row, int col)

Creates a maze coordinate object with the given row and column.

int getRow()

Returns the row of the coordinate

int getCol()

Returns the column of the coordinate

[C++] Node type and ListType (this is the only part of the code handout with C++ code):

struct Node {

int data;

Node * next;

Node(int item); // create a Node with the given value and NULL next field

// create a Node with the given data value (item) and next field (n)

Node(int item, Node * n);

};

typedef Node * ListType;
