Write a method weave that takes two arrays of ints, a and b, and that returns an array that contains the elements of a and b in the order.a[0], b[0], a[1], b[1], etc. If one of the arrays a or b is longer than the other, just add the extra elements at the end of the array.
Create a class called invoice that a hardware store might use to represent an invoice for an item sold at the store. An invoice should include four pieces of information as instance variables, a part number(type string), a part description (type string), a quantity of the item being purchased (type int) and a price per item(double).Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value .If the quantity is not positive, it should be set to 0.If the price per item is not positive ,it should be set to 0.0.
Write a test app named InvoiceTest that demonstrate class Invoice’s capabilities.
Create a class called Employee that includes three instance variables, a first name (type string), a last name (type string) and a monthly salary (double). Provide a constructor that initializes the three instance variable .Provide a set and a get method for each instance variable. If The monthly salary is not positive, do not set its value.
Write a test app named EmployeeTest that demonstrate class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a 10% raise and display each display each employee’s yearly salary again.

Write a Java program that declares three variables of int type, q, d, and n, to
represent a set of number of coins a user must insert in order to buy a pack of cookie from the vending machine.
Use three nested while loops (must be while loops) to display all possible combinations of q, d, and n, as shown below.
You need to use an if statement within inner-most while loop to evaluate a Boolean condition based on the formula: 0.25q + 0.1d + 0.05n = 0.65.
