Consider the following class definitions. public class Bike{private int numWheels = 2;// No constructor defined}public class EBike extends Bike{private int numBatteries;public EBike(int batteries){numBatteries = batteries;}}The following code segment appears in a method in a class other than Bike or EBike. EBike eB = new EBike(4);Which of the following best describes the effect of executing the code segment?
A А. An implicit call to the zero-parameter Bike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
B An implicit call to the one-parameter Bike constructor with the parameter passed to the EBike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
C Because super is not explicitly called from the EBike constructor, the instance variable numWheels is not initialized. The instance variable numBatteries is initialized using the value of the parameter batteries.
D The code segment will not execute because the Bike class is a superclass and must have a constructor.
E The code segment will not execute because the constructor of the EBike class is missing a second parameter to use to initialize the numWheels instance variable.

You have just been hired as an information security engineer for a large, multi-international corporation. unfortunately, your company has suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets are private and secured. credit-card information was compromised by an attack that infiltrated the network through a vulnerable wireless connection within the organization. the other breach was an inside job where personal data was stolen because of weak access-control policies within the organization that allowed an unauthorized individual access to valuable data. your job is to develop a risk-management policy that addresses the two security breaches and how to mitigate these risks. requirementswrite a brief description of the case study. it requires two to three pages, based upon the apa style of writing. use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. use a double-spaced, arial font, size 12.

Problem 1 - hashing we would like to use initials to locate an individual. for instance, mel should locate the person mark e. lehr. note: this is all upper case. generate a hash function for the above using the numbers on your telephone. you know, each letter has a number associated with it, so examine your telephone keypad. generate 512 random 3 letter initials and take statistics on a linked list array size 512 to hold this information report how many have no elements, 1 element, 2 elements, does this agree with the hashing statistics distribution?
