The code:

double[] list = new double[100];

does the following:

1. Declares and initializes an array of double values: The variable list is declared as an array that can hold elements of type double.

2. Allocates memory for the array with 100 elements: The keyword new is used to allocate space in memory for 100 double elements. The size of the array is fixed at 100.

3. Initializes all elements to the default value 0.0: In Java, numeric types (such as double) are initialized to their default values (which is 0.0 for double) when a new array is created. This means all 100 elements of the array are initialized to 0.0 initially.

In short, this code creates an array named list that can hold 100 double values, all starting with the value 0.0.
