Method Detail

getProblem

public static void getProblem(java.lang.String topic,
                              int numberSolvedSoFar,
                              java.util.Vector codeText,
                              Behavior behavior)

Provides the code and behavior of the (n+1)th problem on a topic.

Parameters:

topic - String representing the topic for which a problem is desired

numberSolvedSoFar - The number of problems that have been provided so far to the user (and should be skipped before generating the next problem)

codeText - Vector that will contain the code for the problem

behavior - Behavior object that holds the behavior of the problem

getCodeProblem

public static void getCodeProblem(java.lang.String topic,
                                  int numberSolvedSoFar,
                                  java.util.Vector codeText,
                                  Behavior behavior)

Provides the code and behavior of the (n+1)th code-analysis problem on a topic.

Parameters:

topic - String representing the topic for which a problem is desired

numberSolvedSoFar - The number of problems that have been provided so far to the user (and should be skipped before generating the next problem)

codeText - Vector that will contain the code for the problem

behavior - Behavior object that holds the behavior of the problem

getExpressionProblem

public static void getExpressionProblem(java.lang.String topic,
                                        int numberSolvedSoFar,
                                        java.util.Vector codeText,
                                        Behavior behavior)

Provides the code and behavior of the (n+1)th expression-evaluation problem on a topic.

Parameters:

topic - String representing the topic for which a problem is desired

numberSolvedSoFar - The number of problems that have been provided so far to the user (and should be skipped before generating the next problem)

codeText - Vector that will contain the code for the problem

behavior - Behavior object that holds the behavior of the problem

setLanguage

public static boolean setLanguage(java.lang.String inLanguage)

Sets the language for which problems should be generated

Parameters:

inLanguage - String representing the programming language for which problems are desired

Returns:

True if the language was successfully changed, and false otherwise (if invalid language was specified).

main

public static void main(java.lang.String[] args)

Generates the (n+1)th problem on the specified topic, and prints its code, explanation, output and errors.

Parameters:

args - Command line arguments, the first being the topic and the second being the number of problems generated so far
