java calculator code

The modified calculator Code has the following problem: If you need to add a new operation class, in addition to modifying the interface code, you also need to add a new statement in the switch of operaationfactory! Using C # reflection technology can solve the problem well. The following code does not use DLL. For exa

The following small series for everyone to bring a PHP mortgage calculator instance Code, equal and principal interest, equal to the principal. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting. Examples are as follows: DEBX (); function Debx () {$dkm = 240;//Loan month, 20 is 240 months $dkTotal = 10000;//Total loan $d

The first chapter in "big talk Design Patterns" is an example of a simple calculator built with a simple factory model, there is a factory class operaationfactory on the P10-P11 page in the book to construct instances of each operation class, but there is a problem here: if you need to add a new operation class, in addition to modifying the interface code, you also need to add a new statement in the switch
