(enable geometricobject comparable) modify the geometricobject class to implement the comparable interface, and define a static max method in the geometricobject class for finding the larger of two geometricobject objects. draw the uml diagram and implement the new geometricobject class. write a test program that uses the max method to find the larger of two circles and the larger of two rectangles.

Dean wants a quick way to look up staff members by their staff id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text “invalid staff id” should be displayed by the formula. (hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.

Match the sentence fragment in the first column with the appropriate ending in the second column. a little per favore?
