Need Help with java assignment

Hi I need help with this java assignment if someone can help me I would gladly appreciate it. Thank you.

1.Array multiplication: Write a program that creates an array of 10 numbers.
Have the user input the numbers into the array as double. Then take all of
the numbers and multiply them. Use methods to enter in the numbers into
the array and have the main method output it. (10 points)

  1. Evens and odd: Write a program that allows the user to enter in numbers. Let
    user enter 10 numbers. Once the numbers have been entered, write methods
    that lists how many even and odd numbers there are in the array. Have one
    method for listing even numbers and another for odd. (10 points)

  2. Duplicates and order: You are given an int array that contains these
    numbers: 3, 4, 6, 5, 9, 11, 20, 20, 17, 8, 10, and 8. Write a program that first
    orders(sorts) the number and then remove the duplicates. Have methods that
    order the number and another method to remove the duplicate numbers. (20

  3. Identical: Write a program that has the user enter number for two int arrays.
    Each array must be of length 5 and there should not be any duplicates in
    each array. Once the user completes entering in numbers, test to see if the
    two arrays have identical numbers or not. If there are any identical numbers,
    print them. (30 points)

  4. Write a program to make a diamond using nested loops. (30 points)

Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:

Thanks for info! Very helpful
