Answer:
Replace the comment with:
(c) double hours = Math.abs (marker1 - marker2) / 60.0;
Explanation:
See attachment for right presentation of question
Analyzing the options:
(a): May return a negative result
This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.
This literally is not different from marker1 - marker2
(b): Incorrect expression
This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.
(c) This option is correct
This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)
(d) & (e) Integer division
When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
Answer:
Initialize the “longest word” by an empty string and update it when a longer word is found
Explanation:
import java.util.stream.Stream;
public static String findLongest(String[] spellingList) {
return Stream.of(spellingList).reduce("", (longestWord, word) -> (
longestWord.length() < word.length() ? word : longestWord
));
}
Answer:
Each description of a PC needs to clarify how the PC handles data: numbers, text, pictures, sound, films, directions.
Using bits to represent data implies that the computer has to use a lot of memory since every character has a group of bits representing it.
The PC is an electronic gadget. Every one of its wires can either convey electric flow or... not convey current. Thus, similar to a light switch, it sees just two states. Incidentally, this is sufficient to make the entire thought work. Indeed, any framework that can speak to in any event two states can speak to data. Take, for instance, the Morse code that is utilized in telecommunication. Morse is a sound transmission framework that can convey a short signal (spoke to by a dab) and a long beeeeeep (spoke to by a scramble). Any letter or number can be spoken to by a mix of these two images. Snap here to see a Morse interpreter.
Explanation:
Essentially with PCs. To speak to a number, we utilize the parallel number-crunching framework, not the decimal number framework that we use in regular day to day existence. In the double framework, any number can be spoken to utilizing just two images, 0 and 1. (Morse is nearly, yet not exactly (because of the delays between letters) a paired framework. A framework firmly identified with Morse is utilized by PCs to do information pressure (more about this later).

Answer:
Following are the program definition in the Java Programming Language.
//define a class
public class Clock
{
//set integer type variable and initialize value
private int hours=12;
//set boolean type variable and initialize value
private boolean isTicking=true;
//set integer type variable and initialize value
private Integer diff=5;
}
Explanation:
Following are the description of Code.
- Firstly define a class "Clock" with the "private" access modifier.
- Then, set the integer data type variable "hours" with the "private" access modifier and assign value 12 in that class.
- After that, set the boolean data type variable "isTicking" with the "private" access modifier and assign value "true".
- Finally set Integer class variable "diff" with the the private access modifier and assign value 5.
