Explanation of Solution
Government on data breaches:
“Yes”, the government could do more for the victims of the breach. Some of them are mentioned below:
- The government could announce a data protection bill that would protect the privacy of internet users could end up criminalizing the only people working to uncover abuses of personal data.
- The government could provide free online services that exist to help consumers discover which services they use have been breached, and what information was lost as part of the breach...

Question 2 (10 Points): String vs. StringBuilder
Create a Question2.java file and finish the following tasks:
Task 1.
a) Create a 1D array of integers to store 50 integers.
b) Store values from 0 to 49 in the array you just created.
c) Create a new String Object using no-arg constructor.
d) Using for loop to add the array elements one by one to the String (one per loop iteration)
Hint: to append an element to a String, use the + operator.
e) Output the String on the console. Record and display a run-time it took to append all
integers to the String (record run-time of 1.d.)). Please submit a screenshot. The
screenshot should match the following example:
012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849
it took 196708 nanoseconds to append 50 integers to the String.|
Hint: You can use the following statements to record run-time.
long begin, end, time; // we will measure time it took
begin = System.nanoTime(); //we measure in nanoseconds.
// put…
Answer this Java OOP question below:
Discuss the challenges and benefits of using multiple levels of inheritance in a class hierarchy. How can deep inheritance structures impact the maintainability and readability of code?
Answer the Java OOP question below:
Explain the relationship between a superclass and a subclass. How do the principles of encapsulation and abstraction play a role in this relationship? In your experience, how do you decide what should be included in a superclass versus a subclass? Share an example where a well-defined superclass-subclass hierarchy improved your code.
