will create the array intArray with two elements and initialize it with zero values, the default

value for numbers. The reason for the new keyword is that an array is actually an object in Java.

Objects in Java are created using the new keyword, as we shall see in Chapter 4.

Array elements are counted from zero, so

intArray[0] = 1;

assigns the value of 1 to the first element of

intArray.

Note that once an array is created, its

size cannot be changed.

An example of all this is the 0utputArray program, which assigns the values of 1 and 2

to an integer array and outputs the results.
