Class complex

java.lang.Object
  qcnn.complex

public class complex
extends java.lang.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. % java complex a = a = 5.0 + 6.0i b = -3.0 + 4.0i c = -39.0 + 2.0i d = -39.0 + -2.0i e = 5.0
