Creates an ArrayList, called al that can store integers
Fills the al ArrayList with 10 random integer numbers between 1 and 100
Prints the content of al
Removes the first element of al.
Prints the removed element in step d.
Prints the content of al again.

PART 1 Modify the class ArrayList given in Exercise 1 by using expandable arrays. That is, if the list is full when an item is being added to this list, the elements will be moved to a larger array. The new array should have twice the size of the original array. Using the new class ArrayList, write a program to store 1,000 random numbers, each in the interval [0, 500]. The initial size of the array in the class should...
//Java (Sort ArrayList) Write the following method that sorts an ArrayList: public static > void sort(ArrayList list) Write a test program that does the following operations: 4. Creates an empty ArrayList of Integer elements; 5. Generates 20 integer values, drawn at random between 0 and 9 (included), and adds them to the array list; 6. Calls the method sort and prints both the original list, and the sorted one.
Write a complete Java program called MethodTest according to the following guidelines. The main method hard-codes three integer values into the first three positions of an array of integers calls a method you write called doubleEachValue that takes an array of integers (the one whose values you hard-coded in main) as its only argument and returns an ArrayList of integers, with each value in returned ArrayList equal to double the correspondingly indexed value in the array that is passed in...
Please write in java program Write an application that generates 100 random integers between 1 and 75 and writes them to a file named "file_activity.txt". Read the data back from the file and display the following: The sum of the numbers in the file The average of the numbers in the file The numbers in the file in increasing order To sort an array: int[] arr = new int[20]; Arrays.sort(arr); -- this sorts an array To sort an ArrayList: ArrayList<Integer>...
Write a program in C that creates an array of 100 random numbers from 0-99. The program sums the random numbers and prints the sum. It then writes the numbers to a new file using open, close and write. Then looks in the current directory for files that match the pattern “numbers.XXXX”. For each file, open the file and read the file. You can assume that the file will contain 100 integers. Sum the integers. Print the filename and the sum...
We use bluej for our JAVA program. If you can help id greatly
appreciate it.
Create a new Java program called Flip. Write code that creates and populates an array of size 25 with random numbers between 1-50. Print the array. Print array in reverse.
A java exercise please!
Write a static method named swapHavles that takes an ArrayList of integers as a a parameter and returns a new ArrayList that has every element in the second half of the original ArrayList swapped with every element in the first half of the original ArrayList. Note: • You can assume that the ArrayList passed to this method as a parameter always contains an even number of elements and will always contain at least two elements. For...

Recursion Write and run a program that reads in a set of numbers and stores them in a sequential array. It then calls a recursive function to sort the elements of the array in ascending order. When the sorting is done, the main function prints out the elements of the newly sorted array Hint: How do you sort an array recursively? Place the smallest element of the array...
11.3 (Subclasses of Account) In Programming Exercise 9.7, the Account class was defined to model a bank account. An account has the properties account number, balance, annual interest rate, and date created, and methods to deposit and with- draw funds. Create two subclasses for checking and saving accounts. A checking account has an overdraft limit, but a savings account cannot be overdrawn. Draw the UML diagram for the classes and implement them. Write a test program that creates objects of...
