I already have the class working. I just need to print it sorted by the length of name, and by GPA from class collections and arrays. My current code is as follows. The image contains a segment of Java code that demonstrates sorting a list of `Student` objects based on two different criteria: name length and GPA. The code is structured in a block with comments and is divided into several key parts:1. **Copying and Sorting by Name Length (Ascending):** - The code first displays a message indicating that the students are being sorted by name length in ascending order. - It uses a `for` loop to iterate over the `copy1` list and prints out each `Student` object.2. **Copying the List and Sorting by GPA (Descending):** - A new copy of the `Student` list is created as `copy2`. - The list is then sorted by GPA in descending order using the `Collections.sort()` method with a custom `Comparator`: - If the GPA of `s1` is greater than `s2`, it returns -1. - If the GPA of `s1` is less than `s2`, it returns 1. - Otherwise, it returns 0 for equal GPAs. - A message is printed to indicate the sorted order.3. **Copying to an Array and Sorting by Name Length (Ascending):** - An array `array1` of `Student` is created with the same size as the original list. - The list is converted to an array using `list.toArray(array)`. - The array is sorted by name length using `Arrays.sort()` with a custom `Comparator`: - It compares the lengths of the names and sorts them in ascending order. - It then iterates over the array and prints out each `Student` object.This code is a practical example of using Java collections and arrays to manipulate and sort data, illustrating the implementation of custom comparator logic for sorting purposes. ```javaimport java.util.Arrays;import java.util.Collections;import java.util.Comparator;import java.util.LinkedList;public class Student { private String name; private double gpa; public Student(String name, double gpa) { this.name = name; this.gpa = gpa; } public String getName() { return name; } public double getGpa() { return gpa; } public String toString() { return "(name," + name + " Gpa: " + gpa + ")"; } public static void main(String[] args) { LinkedList list = new LinkedList(); list.add(new Student("Kyle", 3.4)); list.add(new Student("Dog", 4.0)); list.add(new Student("Jeff", 3.97)); list.add(new Student("Manny", 1.9)); list.add(new Student("Wog", 5.1)); // taking a copy of list for sorting, so that sorting will not affect the initial list LinkedList copy1 = new LinkedList(list); // with a custom Comparator, sorting copy1 list using compare method by name length Collections.sort(copy1, new Comparator() { public int compare(Student s1, Student s2) { // this method will return a negative value if s1 name length // is before s2, positive value if s1 needs to come after, // zero if they have same order. return s1.getName().length() - s2.getName().length(); } }); for (Student s : copy1) { System.out.println(s); } }}```### Explanation:This Java program defines a `Student` class with two private fields, `name` and `gpa`, and provides methods to access these fields (`getName` and `getGpa`). The `toString` method returns a string representation of the `Student` object.In the `main` method, a `LinkedList` of `Student` objects is created and populated with students having different names and GPAs. A copy of this list (`copy1`) is created for sorting purposes, ensuring the original list remains unaffected.The program utilizes the `Collections.sort` method with a custom `Comparator` to

Above in the code, there is already a compare method exist for the array to be sorted using the GPA.…

Getting the Concatenated Number In the code editor, you will see that there's a globally declared integer array named, dataset. Additionally, there's a function declaration for the function getConcatenatedNumber(int n). Your task is to define the getConcatenatedNumber function. This will accept an integer n and will perform some operations on the global array. If the passed integer n is an even number, you need to concatenate all the integers located in the even indices (special case: 0 index is considered as even here). If the passed integer n is an odd number, you need to concatenate all integers located in the odd indices. Since 0 is neither odd or even, you need to concatenate all the integers in the array if n is 0. Afterwards, you need to add the inputted integer n three times to the concatenated number and return the result. In the main(), ask the user to input the value of n, call the function getConcatenatedNumber and pass the value of n, and then print the result. SAMPLE:…
