The new operator is used to create objects, that is, instances of classes and arrays. It is used with a constructor call to instantiate classes (see Section 4.4, p. 117), and with the  notation to create arrays (see Section 4.1, p. 100). It is also used to instantiate anonymous arrays (see Section 4.1, p. 104), and anonymous classes (see Section 7.5, p. 308).
Pizza onePizza = new Pizza(); // Create an instance of Pizza class.
The  notation is used to declare and construct arrays and also to access array elements (see Section 4.1, p. 100).
int anArray = new int;// Declare and construct an int array of 5 elements. anArray = anArray; // Element at index 4 gets value of element at index ...
