Create a new version of the class StockPurchase so that it represents the purchase of n shares of stock at d dollars per share. The revised class has the data fields share and cost, a constructor to initially set both data fields, and the accessor methods getNumberOfShares and getCostPerShare. Create a new version of the class StockLedger to contain an instance of a deque instead of a queue. The method buy creates an instance of StockPurchase and places it at the back of the deque. The method sell is now more involved. It must remove a StockPurchase object from the front of the deque and decide whether that object represents more shares than the number sold. If it does, the method creates a new instance of StockPurchase to represent the shares that remain in the portfolio. It then adds that instance to the front of the deque, since these shares would be sold next. Think about how you will handle the case when the object removed doesn't contain enough shares to satisfy the sale. Write a deque class that implements DequeInterface. java. The implementation will use a doubly linked list. You can find the interface and DLLNode. java in the Lab 3 folder in Files on canvas. Your client code from Part 1 should work with Part 2.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
