Even though Java does not have a constant type, you can achieve the same effect by declaring and initializing variables that are static, public, and final. After the variables have been initialized, their value cannot be changed. You can then access the constant value using the name of the variable joined to the name of its class with a period. This code was tested using JDK1.1.6 under Win95:
class Constants02{ public static void main(String[] args){ System.out.println("pi = " + Constants.pi); System.out.println("e = " + Constants.e); }//end main}//end class Constants02//=======================================================//class Constants{ public static final double pi = 3.14159; public static final double e = 2.71828;}//end class Constants
