Answer:
- import java.util.Scanner;
- public class Main {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Please enter two characters: ");
- String inputStr = input.nextLine();
-
- if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
- System.out.println("Biology");
- }
- else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
- System.out.println("Computer Science");
- }
- else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
- {
- System.out.println("Information Technology and Systems");
- }
- else{
- System.out.println("Invalid major");
- }
-
- int num = Character.getNumericValue(inputStr.charAt(1));
-
- if(num >= 1 && num <= 4){
- switch (num){
- case 1:
- System.out.println("freshman");
- break;
- case 2:
- System.out.println("sophomore");
- break;
- case 3:
- System.out.println("junior");
- break;
- case 4:
- System.out.println("senior");
- break;
- }
-
- }
- else{
- System.out.println("Invalid year status");
- }
-
- }
-
- }
Explanation:
The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.
The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.
Answer:
B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct
Answer:
Let the customer vent and then restart the conversation
Explanation:
It is best for Derek in this situation allow the customer say everything on his or her mind about the problems at hand. This will help Derek identify and understand the problems and fix them accordingly. However, he'd need to start the world all over again to achieve this.

The acronym RFID (Radio Frequency Identification) describes
networked devices that contain microcomputers but are not thought of as
computing devices, such as refrigerators, automobile components, light
bulbs, and industrial control devices. RFIDs are battery-powered sensors that gather and transmit data to a reading device. Some sensor based technologies are scanning electron microscopes, LiDAR,radar, GPS, x-ray, sonar, infrared and seismic.
