in Java: this {ArrayList} is a type of class called ....... class that offers some useful methods for working with arrays these methods include (mention four methods):

public static ArrayList findExactString(String s, ArrayList myArray) { return null; } // Use the above method, findExactString, as a helper method to implement addWithoutDuplication method. The addWithoutDuplication method has the following properties: 1- It takes two arguments, a string s and an ArrayList myArray of type string. 2- It returns an integer which represents the number of occurrences of the string s in myArray while attempting to add it. 3- If myArray is null, it returns -1 4- If adds the string s to the end of the ArrayList myArray if the string s is not already there. public static int addwithout Duplication(String s, ArrayList myArray) { return -1;

Java program please

Extend the Array class adding the following two newmethods:A)  the method called min that returns the smallest numberin the array.E.g., applying min to the array [−3, 2, 0, −10, 9, 7], we get −10.B) the method called reverse that reverses the array.E.g., applying reverse to the array [−3, 2, 0, −10, 9, 7], we change itto [7, 9, −10, 0, 2, −3]. USE THE JAVA CODE BELOW TO ADD ON PLEASE public class Array {private int[] elems;private int nElems;public Array(int size) {if (size < 0) {throw new IllegalArgumentException();}elems = new int[size];}public void print() {System.out.print("[");for (int i = 0; i < nElems; ++i)if (i < nElems - 1) {System.out.print(elems[i] + ", ");} else {System.out.print(elems[i]);}System.out.println("]");}public void insert(int element) {// if the array is full, increases its sizeif (elems.length == 0) {int[] extendedElems = new int[1];elems = extendedElems;}if (elems.length == nElems) {int[] extendedElems = new int[nElems * 2];for (int i = 0; i <…

True or False? In Java, an array is a primitive type that need not be instantiated.

Language: Java Write a class encapsulating the concept of daily temperatures for a week with a single dimensional array of temperatures. Write the following methods: A constructor accepting an array of seven temperatures as a parameter. Accessor, mutator, toString() and equals() methods A method returning how many temperatures were below freezing. A method returning an array of temperatures above 100 degrees. A method returning the largest change in temperature between any two consecutive days. A method returning an array of daily temperatures, sorted in descending order (do not use a built-in Java class, modify one of the sorting algorithms in the textbook). Write a client class to test all the methods in your class.

Code these three methods.

Please help me make a game with Java. The game should have only a class and needs to include at least 3 of the following AP topics: String Array, ArrayList, 2D Array Interfaces and/or Abstract classes Polymorphism Inheritance Searching Algorithms Sorting Algorithms Recursion   You also need to include a new topic that is different than the above. Once you finish creating the game, please show me the new topic that you included and let me know what are the other 3 topics that you chose from the list above and what was challenging.

JAVA Which is true about arrays and methods? A. Arrays cannot be passed to methods B. Passing an array to a method creates a copy of the array within the method C. An array is passed to a method as a reference D. A programmer must make a copy of an array before passing the array to a method

Write a java method that receives a reference to an array of integers and then sorts only the non-perfect numbers. if a number is perfect then it must remain in its current location in the array.   Notes: 1) You are not allowed to use the Arrays.sort() method or any other ready-made sorting method. 2) You can not define new arrays. Your sorting must be in-place. 3) A number if perfect if the some of its divisors is equal to the number itself. For example the number 6 is perfect because the sum of its divisors is 1+2+3 = 6 while 8 is not perfect because the sum of its divisors is 1+2+4 = 7 which is not equal to 8.
