Create a base class base with an abstract print() method that is overridden in a derived class derived. the overridden version of the method prints the value of an int variable defined in the derived class. at the point of definition of this variable, give it a nonzero value, say, 11. in the base class constructor, call this method. in create an object of the derived type, and then call its print() method. explain the results. (1 point) 5. create three interfaces (you choose their names), each with two methods (you choose their return types and signatures). inherit a new interface that combines the three, adding a new method. create a class by implementing the new interface and also inheriting from a concrete class. now write four methods, each of which takes one of the four interfaces as an argument. in create an object of your class and pass it to each of the methods. (1 point)

Draw the hierarchy chart and design the logic for a program that calculates service charges for hazel's housecleaning service. the program contains housekeeping, detail loop, and end-of-job modules. the main program declares any needed global variables and constants and calls the other modules. the housekeeping module displays a prompt for and accepts a customer's last name. while the user does not enter for the name, the detail loop accepts the number of bathrooms and the number of other rooms to be cleaned. the service charge is computed as $40 plus $15 for each bathroom and $10 for each of the other rooms. the detail loop also displays the service charge and then prompts the user for the next customer's name. the end-of-job module, which executes after the user enters the sentinel value for the name, displays a message that indicates the program is complete.

What are compression artifacts? 1) visible defects in the picture caused by the nature of the compression algorithm. 2) numbers that tell a web server how much to compress a picture for faster transmission. 3) invisible defects in the picture preserved by lossless compression. 4) numbers that tell a photo editing program how much to compress a picture for faster transmission.

The instruction ishl (shift left integer) exists in jvm but not in ijvm. it uses the top two values on the stack, replacing the two with a single value, the result. the sec- ond-from-top word of the stack is the operand to be shifted. its content is shifted left by a value between 0 and 31, inclusive, depending on the value of the 5 least signifi- cant bits of the top word on the stack (the other 27 bits of the top word are ignored). zeros are shifted in from the right for as many bits as the shift count. the opcode for ishl is 120 (0x78).a. what is the arithmetic operation equivalent to shifting left with a count of 2? b. extend the microcode to include this instruction as a part of ijv.
