- java Write a program to do the following: Create an ArrayList of Student. Add 7 elements to the ArrayList. Use for each loop to print all the elements of an ArrayList. Remove an element from an ArrayList using the index number. Remove the element from an ArrayList using the content (element name).Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value.

- Create a Java array FirstArray, type int, length 10. Initialize it with the multiple of 2. Print the array using comma separators. (Hint: Use Arrays.toSring method. You need to import java.util.Arrays package) Print the array with vertical line (|) separator. DO NOT put the vertical line after last element.Using Java You will write the code to perform the following operations using the ArrayList class: Implement a Shoe class, encapsulating the concept of a shoe A shoe has a color, size, and brand. Implement a ShoeStore class, encapsulating the concept of a shoe store. Use the ArrrayList of Shoe objects. Fill the ArrayList object with Shoe objects. Implement a ShoeSearchEnginge class Print Shoe objects in the ArrayList. color: white size: 11 brand: Anne Klein color: yellow size: 13 brand: Calvin Klein color: black size: 9 brand: COACH color: blue size: 5 brand: CLARK color: black size: 7 brand: Cole Han color: blue size: 15 brand: FitFlo color: red size: 9 brand: CLARK Find all Shoe objects with CLARK as a brand in the ArrayList. Find the largest size of a Shoe object in the ArrayList.Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…
- JAVAWrite a program that searches person's name and display all matched name. For example, if a user inputs the letter "Davis", the program searches all name which includes "Davis" in an array. Then, display all matched names on the screen. You must declare a single dimensional array which has all people’s name. Use methods of string classgetListRowIndices Method public static java.util.ArrayList<java.lang.Integer> getListRowIndices(int[][] array, int rowLength) This method returns an ArrayList with the indices of rows of the two-dimensional having a length that corresponds to rowLength. You may only use one auxiliary method. The method should create an ArrayList that is passed to the auxiliary in order to place the indices (if any). If no indices are found, an empty (size of 0) ArrayList will be returned. You can assume the array parameter will not be null and every row of the two-dimensional array has an array with a size of at least 0. Your implementation must be recursive and you may not use any loop construct. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: array - rowLength - Returns: ArrayList<Integer>5. How to find all the leaders in an integer array in java? An element is leader if it is greater than all the elements to its right side. And the rightmost element is always a leader. For example int the array {16, 17, 4, 3, 5, 2}, leaders are 17, 5 and 2..
