Concept explainers
Suppose the following code is written to reverse the contents in an array, explain why it is wrong. How do you fix it?
int[] list;: {1 , 2 , 3 , 5 , 4 };
for (int i ;: 0 , j ;: list.length- 1 ; < 1ist. 1ength; i ++, j --) {
// Swap list[i] with list[j]
int temp;: list[i];
list[i] list[j] ;
list[j] ;: temp ;
}

- Duplicate Set This function will receive a list of elements with duplicate elements. It should add all of the duplicate elements to a set and return the set containing the duplicate elements. A duplicate element is an element found more than one time in the specified list. The order of the set does not matter. Signature: public static HashSet<Object> duplicateSet(ArrayList<Object> list) Example: INPUT: [2, 4, 5, 3, 3, 5] OUTPUT: {5, 3}arrow_forwardQ1. Write the following method that returns thesmallest element in an ArrayList:public static <E extends Comparable<E>> E min(ArrayList<E> list).arrow_forwardTrue or False? An initializer list can be used to instantiate an array object instead of using the new operator.arrow_forward
- Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Birdarrow_forwardProject Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverse Words (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Birdarrow_forward18. The mean of a set of numbers is the average computed by dividing the sum of the numbers by the quantity of the numbers. Complete method getMean below. // precondition: // postcondition: list is a non-empty array of integers. getMean returns the mean of the integers stored by list. public static double getMean(int[] list) {arrow_forward
- Subject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.arrow_forwardSubject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screenb) In the same program, insert an element in the above ArrayList at index 2. The resulting Array Listmust be one element larger. Print the resulting list to the screen.c) In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.d) In the same program, remove the element at the last index of the Array List. Print the resulting list tothe screen.e) In the same program, use a 'for' loop to print each element of the Array List to the screen.f) Create a class named ArrayListManager. Into this class, code a method which prints to the screenevery element of an Array List of strings placed at an odd index. Hint: use a modulus.arrow_forwardList<String> colors = Arrays.asList(“red”, ”green”, ”blue”, "yellow","purple", "green","red"); Write a line of code to create and pass this list of colors to another type of collection so that the colors are sorted and contain duplicates .arrow_forward
- 6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between get and index of? 11. Print the values of the array list using Iterator class. 12.. Delete all the values of the array list using clear function. 13. Print all the values of the array after you execute clear using System.out.println(). what is the result of using clear function? 14. What is the shortcoming of using array List?arrow_forwardAre they equivalent? 1) ArrayList<?> list = new ArrayList(); 2) ArrayList<? super Object> list = new ArrayList<>();arrow_forward6. Consider the following code segment: ArrayList list = new ArrayList(10) ; list.add( "Ali" ); list.add( "Ahmed" ); list.add( "Hassan" ); list.add( 0, "Qasim" ); Which of the following elements will be at index 1 of the list? K Ali Ahmed Hassan Qasimarrow_forward
