You designed a program to create a username using the first three letters from the first name and the first four letters of the

last name. Usernames cannot have spaces. You are testing your program with a user whose name is Jo Wen. What step in the program plan do you need to revisit

Answer:

See Explanation

Explanation:

The question would be best answered if there are options to select from; since none is provided, I will provide a general explanation.

From the question, we understand that, you are to test for Jo Wen.

Testing your program with this name will crash the program, because Jo has 2 letters (3 letters are required), and Wen has 3 letters (4 letters are required)

So, the step that needs to be revisited is when the username is generated.

Since the person's name cannot be changed and such person will not be prevented from registering on the platform, you need to create a dynamic process that handles names whose lengths are not up to the required length.

Now that the classList Array has been implemented, we need to create methods to access the list items.
natima [27]

The following code will be applied to Create the following static methods for the Student class

<u>Explanation:</u>

/* Note: Array index starts from 0 in java so ,, user ask for 1 index then the position will be i-1 , below program is based on this concept if you dont want this way just remove -1 from classList.get(i-1).getName(); ,and classList.add(i-1,student); */

/* ClassListTester.java */

public class ClassListTester

{

public static void main(String[] args)

{

//You don't need to change anything here, but feel free to add more Students!

Student alan = new Student("Alan", 11);

Student kevin = new Student("Kevin", 10);

Student annie = new Student("Annie", 12);

System.out.println(Student.printClassList());

System.out.println(Student.getLastStudent());

System.out.println(Student.getStudent(1));

Student.addStudent(2, new Student("Trevor", 12));

System.out.println(Student.printClassList());

System.out.println(Student.getClassSize());

}

}

/* Student.java */

import java.util.ArrayList;

public class Student

{

private String name;

private int grade;

//Implement classList here:

private static ArrayList<Student> classList = new ArrayList<Student>();

public Student(String name, int grade)

{

this.name = name;

this.grade = grade;

classList.add(this);

}

public String getName()

{

return this.name;

}

//Add the static methods here:

public static String printClassList()

{

String names = "";

for(Student name: classList)

{

names+= name.getName() + "\n";

}

return "Student Class List:\n" + names;

}  

public static String getLastStudent() {

// index run from 0 so last student will be size -1

return classList.get(classList.size()-1).getName();

}

public static String getStudent(int i) {

// array starts from 0 so i-1 will be the student

return classList.get(i-1).getName();

}

public static void addStudent(int i, Student student) {

// array starts from 0 so, we add at i-1 position

classList.add(i-1,student);

// remove extra student

classList.remove(classList.size()-1);

}  

public static int getClassSize() {

return classList.size();

}

}

3.1.5 Which network component connects a device to transmission media and allows the device to send and receive messages?
Rom4ik [11]

Answer:

Network Interface Card (NIC)

Explanation:

Also called Ethernet Card, the Network Interface Card (NIC) allows a computer or any device to make wired or wireless connections with other devices in a network. This connection made possible by the NIC allows the device to send and receive messages in the network.

An application of this is seen in Internet of Things(IoT) where devices communicate with one another. This is actually possible because all of the devices one way or the other have a network interface card.

Elanso [62]

Answer:

import java.util.Arrays;

import java.util.Scanner;

public class num4 {

   public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

       System.out.println("How many numbers? ");

       int n = in.nextInt();

       int []intArray = new int[n];

       //Entering the values

       for(int i=0; i<intArray.length;i++){

           System.out.println("Enter the numbers");

           intArray[i]=in.nextInt();

       }

       System.out.println(Arrays.toString(intArray));

       int min =intArray[0];

       for(int i =0; i<intArray.length; i++){

           if(min>intArray[i]){

               min = intArray[i];

           }

       }

       System.out.println("The Minimum of the numbers is "+min);

   }

}

Explanation:

  • Using Java programming language
  • Prompt the user for the number of values
  • Using Scanner class receive and store in a variable
  • Create an array of size n
  • Using an for loop continuously ask the user to enter the integers
  • Print the array of integers
  • Using another for loop with an if statement, find the smallest element in the array of numbers
  • Output the the smallest number

Suppose you've decided to write a function template that you expect to use in many different source files. Suppose, further, tha
Sladkaya [172]

Answer:

The Solution to the given question can be defined as follows:

Explanation:

Please find the complete question in the attachment file.

In this case, the compiler will try to correct the model type by both the form we used when we try and call the method with both the appropriate form variable. It type of function. Consequently, unless the function in another file is specified, the compiler cannot locate the digital strategy. The point to note here is that only when this code is used, the template code shall be compiled.

The construct component will therefore be efficient so in this case, its connection stage would fail. An undefined connection to the feature <function name> can constitute a possible error in this case. It rules, therefore, address the construction project problem. Furthermore, the template function throughout the main program is generally recommended. It can be solved alternatively because parameters of a template like <function name><type> could be specified throughout the CPP file.
