Question

Complete the following definition of the method below so that it creates and returns an array of 10 InterestAccount objects. • The first InterestAccount object should have the name "customero", the second "customer1", the third "customer2", and so on. • The balance of the first InterestAccount object should be 2000. Each subsequent InterestAccount object should have a balance 1000 greater than the previous. • The interest rate for the first InterestAccount object should be 1.23. All other InterestAccount objects should have an interest rate of 4.56. Begin by declaring an array that can contain references to 10 InterestAccount objects. Use a for loop to populate the array with appropriately constructed InterestAccount objects and, finally, return the array. public static InterestAccount[] createSampleInterestAccounts() { } Next pag
