Write Java code that computes the sum of every other number in an array, starting with the second one, and prints the sum to the standard output (console/terminal). You may assume you have an integer array named intArr. Use Java.

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...

Make sure to use arrays for this assignment. Write a program ThueMorse.java that will take an integer command-line argument n and will printsan n-by-n pattern like the one below. Make sure to include two space characters between each character. example: input= 4 output = + - - + - + + - - + + - + - - +

Write a full Java program to do the following: 1. 2- 3-1 Declare a one-dimensional array of type integer of size 10. Fill the array with the following numbers without hard coding the numbers and without the user input, do the calculation yourself: 5, 10, 15, 20, 25.... Revers the array by moving the elements from first to last second to the one before the last and so on. You have to move the elements to their new locations. Note: Printing the array in reversed order is not acceptable. 4-A Print method to print the array before and after.

Write the following Java code: Create an array of size 10 with elements entered by the user. Print the Array Switch the first and last elements of the array. Shift all elements by one to the right, and move the last element into the first position. Replace all even numbers with 0.

Write a program to do the following task: Declare a two-dimensional array with 3 rows and 4 columns and fill it with random integers in the range of 0 to 100. Then create a one-dimensional array of doubles whose elements are the average values of each of the rows of the two-dimensional array. Output the two-dimensional array with the average of each row displayed at the end of each line.using java programming different method

Create the following program to demonstrate working with arrays in java. Your company pays its sales staff on a commission basis. Each employee receives 500ドル per week plus 6.5% of their sales. For example, a salesperson who sells 10,000ドル worth of products will get a salary of 500 + (10000 * .065) or 1150ドル for that week. You are given the task of creating a program to allow a manager to enter in the sales for 10 employees. (Store them in an array of course.) Then it should display the 10 sales amounts, the 10 salaries for this pay period, and the average salary. (Hint: There are a couple ways to approach this one, here are two ideas: (1) You could create a second array for the salaries and load it at the same time as you gather and store the sales, then loop through the salaries one to find the average, and then you have all the pieces to print. (2) Another solution would be to take in the sales, and then calculate the salaries on the print (which means you don't have to store them in a...

Create a Java program that will perform the following statements.Perform the following items in a continuous manner. The code solution for the next item will be basedon the code performed on the previous item.1. Create an ArrayList named "apostles" and add the following names to it: Juan, Pedro, Lucas,Judas, Mateo, Marcos and Simon.2. Print the size of the ArrayList to the standard output before and after adding the names.3. Use two methods to print the names in standard output.a. Using For loopb. Using Iterator4. Add the name "Philip" at the end, and add the name "Thomas" between the two names "Juan"and "Pedro".5. Remove the name "Judas" using its index position.6. Search the names "Marcos", "James" and "Judas" in the ArrayList "apostles"This part will display the following:Does "apostles" contains Marcos? _______ (it will return a Boolean result)Does "apostles" contains James? _______Does "apostles" contains Judas? _______7. Sort the names of the ArrayList in alphabetical order.8....

Write the following Java program Allocate an array a of ten integers. Put the number 17 as the initial element of the array. Put the number 29 as the last element of the array. Fill the remaining elements with –1. Add 1 to each element of the array. Print all elements of the array, one per line. Print all elements of the array in a single line, separated by commas.
