It is very important to abandon literary theft.
Understand the task about what you are talking about and resort to me if you want help or the help files of the solution
Please solve with understanding because I need these grades so badly.
? My budget is small because I don’t have money left. I apologize, sir.
?Please note that you must include my name in the solution, not your name, you as an assistant.
⭕️The questions below, when you solve them, you must put my name and include screen pictures, because the teacher asks us for proofs, which are screen pictures, so when you start playing the code, make sure to include my name in the solution.
I’ll give you an example if my words are not clear

Q1) Find the issues in the following Java code, then correct them.
public class Rectangular
{
private int length;
private int width;
public Rectangular(int length, int width)
{
this.length = length;
this.width = width;
}
public String area ()
{
return length * width;
}
}
public class RectangularTest
{
public static void main (String[] args)
{
Rectangular r1 = new Rectangular(3,5);
System.out.println(area());
}
} Q2)
Create a Java class for Student with the following requirements:
Create a tester class with the main method with the following requirements.
Each student has two attributes: Name and ID.
Create two constructors. One constructor without parameters to initialize all the instance variables to default values, and another constructor to initialize all the attributes to specific values.
Add all setter and getter methods.
Create two objects from Student class. Create the first object using the default constructor and the second object must set your name and ID.
Print your name and ID using getter methods.
Q3)Suppose you have the following 2 dimensions array:
int arr[][] = {
{ 10, 11, 12, 13, 14 },
{
15, 16, 17, 18, 19 },
{
20, 21, 22, 23, 24 },
{
25, 26, 27, 28, 29 },
{
30, 31, 32, 33, 34 }
};
With the the following rows and columns sizes:
static int rows= 5;
static int columns= 5;
Write a Java programs that uses takes
arr[][] and reverse
(mirror) all rows. For example, the first row should be as the following after
you reverse it 14 13 12 11 10. A screenshot
of your output should also be included in your answer and should display both
the original array and the reversed array.
Sample output:
Q4) What
is the output of the following Java program?

{
Exam
e = new Exam();
this.studyingHours
= 24;
course
= “Math”;
System.out.println(“Exam.studyingHours:
” + Exam.studyingHours);
System.out.println(“e.studyingHours:
” + e.studyingHours);
System.out.println(“e.course:

System.out.println(“course:
” + course);
}
public static void main(String args[])
{

e = new Exam();

references using a proper referencing style (APA).

For this discussion assignment, please provide your response in a minimum of 500 to 750 words.
Explore the fundamental distinctions between static and non-static (instance) methods and variables in Java, comprehensively explaining their essential dissimilarities, use cases, and implications in object-oriented programming. Support your explanation with concrete examples that highlight the practical applications of these concepts. Additionally, analyze the advantages and limitations associated with static and non-static elements, considering factors such as memory management, code organization, and access scopes.
Please include a word count. Following the APA standard, use references and in-text citations for the textbook and any other sources.

Hello,
I need you to program “Java file” you must use “Array” in the programming stage. Otherwise, it’ll not be accepted.
Follow the attached requirements.

In this project, you will be writing a simple database based on an indexed sequential file. You
may write the program in C/C++, Java, or Python. The program will take as a command-line
argument the name of a sequential file. The sequential file should use the “.db” extension. The
program will then present a user command loop that allows the user to add, delete, search for,
and modify records.
Details
The program will take as a command-line argument the name of the sequential file (extension
“.db”). If the file does not exist, then it is created along with the overflow and index file. The
overflow and index files should have the same base name as the sequential file, but with the
“.overflow” and “.index” extensions, respectively. If the sequential file does not exist but the index
or overflow files does, then the existing files must be truncated. That is, the files should be emptied (or deleted and recreated). For simplicity, when the overflow file contains 10 records perform
the merge. Do not forget to update the index file. This can be done by traversing the B-Tree and
updating the “values” associated with each key.
