Question: Create a double array with the values 1.7, 6.4, 8.9, 3.1, and 9.2, and determine the number of elements in the array. Answer: To create and initialize a double array with the values 1.7, 6.4, 8.9, 3.1, and 9.2, you can use the following statement: `double[] myArray = {1.7, 6.4, 8.9, 3.1, 9.2};`. The number of elements in the array can be determined using the length property: `int arraySize = myArray.length;`. In this case, the number of elements in the array is 5.

Step by step solution

Create and Initialize the Double Array

To create and initialize a double array with the given values, you can use the following statement: ```double[] myArray = {1.7, 6.4, 8.9, 3.1, 9.2};``` This statement declares and initializes a double array called `myArray` with the specified values.

Count the Number of Elements in the Array

To count the number of elements in the array, you can use the length property of the array. The following statement accesses the length property of the array and assigns it to an integer variable `arraySize`: ```int arraySize = myArray.length;``` In this case, `arraySize` will store the number of elements in the `myArray`, which is 5 since there are five values provided in the exercise.
