Initializer Lists

You can declare, construct, and initialize the array all in one statement:

int[] data = {23, 38, 14, -3, 0, 14, 9, 103, 0, -56 };

This declares an array of int which is named data. Then it constructs an int array of 10 cells (indexed 0..9). Finally it puts the designated values into the cells. The first value in the initializer list corresponds to index 0, the second value coresponds to index 1, and so on. (So in this example, data[0] gets the 23.)

You do not have to say how many cells the array has. The compiler will count the values in the initializer list and make that many cells. Once an array has been constructed, the number of cells does not change. Initializer lists are usually used only for small arrays.
