Java programer

Hello, I have 4 taks to complete in Java wich is urgent. 1. An array is given: int[] array = {12, 23, -22, 0, 43, 545, -4, -55, 43, 12, 0, -999, -87}. I must make two arrays, one for the postive numbers and one for the negative numbers, also the logic for the sortings. So from array "array" I need to seek all postive elements and to put them in a separate array and that also the same but just for the negative numbers. Also needed is to determine the number of double numbers in the array "array".In that case include also the zeroes (0). The logic must be applied to any combination not just the given numbers.

Every product needs to have these next traits: -Name -Bar code -Base price -Tax Every product has a method to caluclate prices. They are cacluclated by increasing the base price for the precentage of the tax wich is 20% and is constant. Needs to be a netBeans project. 3.
