narmts Save Answer Write a Java program that uses ArrayList and Iterator. It should input from user the names and ages of your few friends in a loop and add into ArrayList. Finally, it should use Iterator to display the data in a proper format. (Hint- Lecture 02: Slide 8) Sample output: List of my Friends Enter name and age [friend# oj Khalid Al-shamri 22.5 Do you want to add another friend (y/n)? y Enter name and age [friend# 1] Rahsed Al-anazi 21.1 Do you want to add another friend (y/n)? y Enter name and age [friend# 2] Salem Al-mutairi 23.7 Do you want to add another friend (y/n)? n Here is the data you entered: 0.

Data Structure & Algorithm: Show by fully java coded examples how any two sorting algorithms work. You should test these with various array sizes and run them several times and record the execution times. At least four array sizes are recommended. 15, 20, 25, 30. It is recommended you write the classes and then demonstrate/test them using another class. Discuss the comparative efficiencies of your two chosen sorting algorithms.
Java - Gift Exchange *** Please include UML Diagram and notes in code Minimum requirements are: At least 1 loop An Array or ArrayList At least 3 Java classes Use methods I am trying to make it so that the program will: Prompt for the number of people included in exchange - If not even it will state that there has to be an even number and ask for the number of people included again (loops). Prompt to enter a participant's first name Prompt for the participant's age Print out the random matching of participants so that everyone gets a gift and everyone gives a gift. Please include UML Diagram
In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…

Write a recursive (no "while" or "for" or any looping statement) method "frequency", which takes as parameters an IntNode myList and an integer element and returns the number of times the integer element appears in myList. public class IntNode. { private int m_data; private IntNode m link; public IntNode (int data, IntNode link) { m data data; m link link; } public int getInfo() {return m_data; } public IntNode getLink () {return m_link; } } public int frequency (IntNode myList, int element) {
Student class is defined as follows. Class Student {int Number String Name} Using the “Student” class write a Java program that reads student’s data on the screen into one dimension array. List the data that you read in array. Test your program for 10 students and show the result list. Note: Just use one array.

Java Lab #1 1. Create an ArrayList a. Fill with 20 random values [1-25] . b. Insert the value -12 at index 3. c. Double all odd values. d. Remove all values 15. e. Remove all multiples of 4 and insert into a new ArrayList called fours. Note: Display the lists after each step.
