assert Exercises

   < Previous  Next >
  1. Write a simple assert statement with just a test expression
  2. Write an assert statement with a test expression and an error message
  3. Replace the /* add assert statement HERE */ with an appropriate assert statement: 
    final int MAX_LOOP_COUNT = 10;
final int COUNTER_THRESHOLD = 50;
int i = 0;
int counter = 0;
while( i < MAX_LOOP_COUNT ){
    int j = 0;
    while( j < MAX_LOOP_COUNT ){
        ++counter;
        if( counter > 50 ){
            return;
        }
        ++j;
    }
    ++i;
}

// Should never reach this line
	    
/* add assert statement HERE */
  4. Add appropriate assert statements for the assumptions in the following helper method: 
    /**
 * Processes the survey results
 * @param name Participant's last name
 * @param age Participant's age
 * @return true if survey results were successful processed, false otherwise
 */
private boolean processSurvey( String name, int age ){

    // Note: It's assumed that the name is at least 2 characters long
    // Note: Can only legally process participants 18 years and older
    
}
