Java Computer Programming, make the deliverables fit into one program.

Extracted text: An array is a consecutive storage for multiple items of the same type. You can store a value in an array using an index (location in the array). You can get a value from an array using an index. An array is like a row of lockers, except that you can't cram lots of stuff into it. You can only store one value at each array index. An array index is like a locker number. It helps you find a particular place to store your stuff and retrieve stuff. There are several ways to declare and create a one-dimensional array. An array named numbers is being instantiated in the following statements: int[] numbers = new int[5]; and int[] numbers = {11, 12, -33, 54, 5}; Unless initialized, the values in an array of int's or double's are automatically initialized to zero. The value stored in an index position of an array is called an element. The first element of an array is considered to be stored in index position zero (aka subscript position zero). To assign or change a value stored in the array, you can use an assignment statement like this numbers [0] = 99; //which stores the value 99 in index position 0. To display an element in an array, you can use the square brackets as in System.out.println(numbers [0]); //to make the value 99 appear. The length property of an array can be used as in int[] scores = {88, 77, 62, 98, 70}; System.out.println (scores.length); which would printout the length of the array named scores which is 5 even though the value 70 is stored in index position 4. Note that length is a public property and not a method. Therefore, parentheses must not be used. Do not confu: this public property with the public method that is available in the String class. Note the difference in the following statements: int[] scores {88, 77, 62, 98, 70}; System.out.println("The length of this array is + scores.length); and String name = "Bob"; System.out.println("The length of this string is " + name.length ()); Once an array has been instantiated, its length can't be changed. You can expand an array indirectly though by creating a bigger array and then copying the contents of the original array into the bigger array.

The method must compute and return the sum of all the values in numbers that are odd. For example, if numbers is {3, 10, 11, 2, 6, 9, 5} then the value 28 should be returned since 3 + 11 + 9 + 5 = 28 is the sum of all the odd values in numbers. 2) Write a static method named replaceEvens that receives the parameter numbers which is an array of int's. The method must replace all elements of numbers that store even values with the negative of that value. That is, if the number 12 is found in a given position of numbers, then the method must replace the 12 with a -12. You can assume that all values in the array are positive numbers greater than zero. 3) Write a static, void method named replaceAll that accepts an array of int's named numbers as well as an int named num. The method must replace all occurrences of num that are found in even-numbered index positions with the value of 3. That is, if the value num is stored in numbers[4] then it must be replaced with the value 3 since 4 is an even number. But if num is found in numbers[5], it must not be replaced since 5 is not an even number. For this exercise, zero is considered to be an even number. The method must work for an array of any size. 4) There is a non-empty array of String's named names. Write a code segment that removes the last letter of the String stored in the very last position of names. For bragging rights and if possible (and I'm not sure if it is), write a single statement that performs this task.
