public class Complex
extends Object
Compilation: javac Complex.java
Execution: java Complex
Data type for complex numbers.
The data type is "immutable" so once you create and initialize
a Complex object, you cannot change it. The "final" keyword
when declaring re and im enforces this rule, making it a
compile-time error to change the .re or .im fields after
they've been initialized.
