Data Structure & Algorithm: Show by fully java coded examples how any two search 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. 10, 20, 30, 40. It is recommended you write the classes and then demonstrate/test them using another class. Discuss the comparative efficiencies of your two chosen search algorithms.

Please help me with this PROGRAMMING 1 JAVA daily practice. Must use linked arrays and one method if possible. Thank you. Create a program that keeps track of information about your friends. The program will keep track of your friends' names and two other pieces of information. One piece of data should be numerical (double, float, int, etc), and the other should be text (String). For instance, maybe you store their name, age, and address. Use Linked Arrays when creating this program. You will ask the user how many friends they have. Then, make the arrays just big enough to hold their data. Ask the user to enter data about their friends. "Please enter the name of friend # 1. Please enter the age of friend # 1...." etc. After they have entered all their friends' data, display the entire database in a nicely formatted chart. Something like this: Name age addressBob 25 123 Main St.Alice...

Arrays of objects. Java programming: How to create and work with an array of objects in Java I wanted to know that supppose that I have 100 employees who are paid on an hourly basis and I need to keep track of their arrival and departure times, and I have also created the class Clock to implement the time of day in a program. I also know that I will use two arraays; one called arrivalTime and the other array called departure time. Each of these arrays will have 100 elements and each element will be a reference variable of Clock type.. For example Clock[] arrival = new Clock[100]. My qeustion is how do I create the objects arrival and departure. Then how could I use the methods f the class clokc. Thank you

Return the First Element in an Array JavaScript Create a function that takes an array containing only numbers and return the first element. Examples getFirstValue ([1, 2, 3]) → 1 getFirstValue ([80, 5, 100])→ 80 getFirstValue ([-500, 0, 50])-500

READY CAREFULLY Java add COMMENT TO CODE, please TEST-CASE on how you would test your solution assumptions and hence your code. Example of cases to be tested for are like : What if the array input which is expected does not exist - that is , input is a null. How should your code handle such a situation ? Maybe output some message like "Null input case, so no output"? What if the length of the array is one ?....so on and so forth. In this assignment you are required programs which takes as input two sorted arrays and returns a new array containing the elements found in both the sorted arrays. It is alright if the input arrays have duplicates, but the returned array should be duplicate free! Below is how the arrays are represented ARRAY1[] = [1, 5, 6, 6, 9, 9, 9, 11, 11, 21] Here length of ARRAY1 is m. ARRAY2[] = [6, 6, 9, 11, 21, 21, 21] Here length of ARRAY2 is n. Array to be returned would be: ARRAY[] = [6, 9, 11, 21] ANSWER THE QUESTION BELOW. Implement the function...

#Steps: Create a Main class. Declare an ArrayList in the main() method and store the given values in it. Create an array called output of the size of the ArrayList. Iterate through for-loop to get each element from the array List and load it into the array using the get() method of the list. Print the array to see the loaded elements. import java.util.ArrayList; import java.util.List; public class Main { public static void main(String[] args) { List<String> nameList = new ArrayList<String>(); nameList.add("Robert"); nameList.add("Samson"); nameList.add("Alex"); nameList.add("William"); System.out.println("Elements of List: " + nameList); // Create an array of the same size as nameList Hint: use size() method // Fetch the elements from the nameList and insert into newly created array // Hint: Use get() method to fetch the elements from...
