Question 1: List three mistakes we can make when using an array.
One mistake when making an array one can forget to encapsulate it, which can cause to many values to be added, or anything else a user could do to mess it up. A second mistake can be declaring the array as the wrong type value which would prevent it from working at all. A third mistake could be to accidently put a double in an array of integers.
Question 2: List at least one configuration of a Scoreboard for each of the above scenarios.
With a new instance of a class the scoreboard would be empty, with a value of 0 high scores.
With a single mutation such as adding a score the method Scoreboard would have 1 value as opposed to the previous amount of zero values. The method isHighScore would return true for the entered score being a highscore seeings as there is only one. The list would be changed through addScore where the score and name would be added to the appropiate position on the list because it is a high score, being the only score. The method getName would return the name of the one high score. Finally the method getNumScores would return the value 1 for the number of high scores.
With multiple mutations the method Scoreboard would hold the top 10 high scores, which means after 10 recorded scores not every score added will make it onto the array. The method, isHighScore will return true if the value entered is one of the top 10 high scores, otherwise it will return false. addScore would add a score and name to the appropiate positon on the list if it is higher then the lowest top score. getName would return the name of the specified positon on the scoreboard as usual. getScore would return the score based on the position you enter as usual. Finally getNumScores would return the number of high scores that are in the scoreboard.
Question 3: Answer the "Testing Questions" descripted in the previous section.
A new instance would have the inputed start and stop values. contains that would return true if the value you give it is equal to or greater than the first value, and less than the second. getWidth would give you the start and stop values. getMin would return the smaller of the two values defining the range, would would be the start value, getMax would return the larger of the two values which would be the stop value. Range intersection would return a new range if the number you input overlaps with your first range and a second range.
There are no mutator methods in this class.
You can find out the largest number, smallest number and the boundaries of the range.
When you pass the range something other than a double.
