- Design and implement an insertSorted() method for the MyArrayList class. The method should receive a single object and insert it in its correct position. You can assume that the calling array is already in a sorted order. The calling array is therefore updated. Follow the three step method for designing the method. Develop the java code for the method. Create a test program to test the method thoroughly using the Integer wrapper class.(b) Write the method isBalanced, which returns true when the delimiters are balanced and returns false otherwise. The delimiters are balanced when both of the following conditions are satisfied; otherwise, they are not balanced. When traversing the ArrayList from the first element to the last element, there is no point at which there are more close delimiters than open delimiters at or before that point. The total number of open delimiters is equal to the total number of close delimiters. Consider a Delimiters object for which openDel is "<sup>" and closeDel is "</sup>".The examples below show different ArrayList objects that could be returned by calls togetDelimitersList and the value that would be returned by a call to isBalanced.Example 1The following example shows an ArrayList for which isBalanced returns true. As tokens areexamined from first to last, the number of open delimiters is always greater than or equal to the number of close delimiters. After examining all…Q1. Let's assume that you have a variable "words" of type ArrayList, already filled with some values. Write the loop to go over each element in the list and count the total number of characters used for all words. In other words, call the method length() on each string and do the sum of all those numbers returned. Do not use a For-Each loop.
- What are the two ways to remove duplicates from ArrayList?3. Create an ArrayList of strings to store the names of celebrities or athletes. Add five names to the list. Process the list with a for loop and the get() method to display the names, one name per line. Pass the list to avoid method. Inside the method, Insert another name at index 2 and remove the name at index 4. Use a foreach loop to display the arraylist again, all names on one line separated by asterisks. After the method call in main, create an iterator for the arraylist and use it to display the list one more time. See Sample Output. SAMPLE OUTPUT Here is the list Lionel Messi Drake Adele Dwayne Johnson Beyonce Here is the new list * Lionel Messi * Drake * Taylor Swift * Adele * Beyonce Using an iterator, here is the list Lionel Messi Drake Taylor Swift Adele BeyonceComplete the method insertInMiddle.
- Please use java. In this assignment, you will implement a class calledCustomIntegerArrayList. This class represents a fancy ArrayList that stores integers and supports additional operations not included in Java's built-in ArrayList methods. For example, the CustomIntegerArrayList class has a “splice” method which removes a specified number of elements from the CustomIntegerArrayList, starting at a given index. For a CustomIntegerArrayList that includes: 1, 2, 3, 4, and 5, calling splice(1, 2) will remove 2 items starting at index 1. This will remove 2 and 3 (the 2nd and 3rd items). The Cu stomIntegerArrayList class has 2 different (overloaded) constructors. (Remember, an overloaded constructor is a constructor that has the same name, but a different number, type, or sequence of parameters, as another constructor in the class.) Having 2 different constructors means you can create an instance of the CustomIntegerArrayList class in 2 different ways, depending on which constructor…Given an ArrayList called myAL that contains the following: ["blue", "red", "yellow"] write code to insert the elements "purple" and "orange" that keeps the list in alphabetical order.need Urgent Requirement: There will one question related to ArrayList class similar to the following question. The following driver has created a an ArrayList of Point objects. write a method that moves all the points with the value of x greater than its value of y to the end of the list. .
- In this assignment, you will compare the performance of ArrayList and LinkedList. More specifically, your program should measure the time to “get” and “insert” an element in an ArrayList and a LinkedList.You program should 1. Initializei. create an ArrayList of Integers and populate it with 100,000 random numbersii. create a LinkedList of Integers and populate it with 100,000 random numbers2. Measure and print the total time it takes to i. get 100,000 numbers at random positions from the ArrayList 3. Measure and print the total time it takes to i. get 100,000 numbers at random positions from the LinkedList 4. Measure and print the total time it takes to i. insert 100,000 numbers in the beginning of the ArrayList 5. Measure and print the total time it takes to i. insert 100,000 numbers in the beginning of the LinkedList 6. You must print the time in milliseconds (1 millisecond is 1/1000000 second).A sample run will be like this:Time for get in ArrayList(ms): 1Time for get in…TASK 7. Generic solution (Methods with Variable-Length Arguments). Review varargs, Implement the following code, test it with different input, make sure it runs without errors.Execute the following statements over initially empty ArrayList myList one after another (cascade). Explain what was changed after each statement (what did it do?) myList.add("z"); ArrayList content: Your explanation (where this output came from): myList.add(0, "a"); ArrayList content: Your explanation (where this output came from): myList.add("t"); ArrayList content: Your explanation (where this output came from): myList.add(2,"w"); ArrayList content: Your explanation (where this output came from): myList.set(0,"b"); ArrayList content: Your explanation (where this output came from):
