Satu line juga.
Okay, okay, dengan deklarasi fungsi dan Sun Java Style Convention jadi tiga
line deh..
public static long factorial(int n) {
return n <= 1 ? 1 : n * factorial(n - 1);
}
Puwas? Puwas? Puwas? :D
Tapi saya pernah lho, liat temen saya coding Factorial dengan secara "rapi
jali" begini:
Factorial factorial = new
org.companyname.projectname.commons.lib.Math.MathImplFactory.getFactorial();
try{
factorial.prepareLowerBound(1);
factorial.prepareUpperBound(10);
System.out.println(factorial.getResult());
} catch (Exception ex){
ex.printStackTrace();
logger.debug(ex);
throw ex;
}
Some "enterprise class" Factorial implementation, methinks :)
wah "hidden gems" maksudnya yang kayak gimana ya?
"Hidden gem" itu cuma kiasan. Figure of speech.
