Conversor De Temperaturas

joaohd · Janeiro 30, 2011

Fugindo um pouco do ambiente lua, decidi aprender alguma outra linguagem mais profissional. O aplicativo não tem muita finalidade mas mesmo assim postarei.

O aplicativo é um conversor entre temperaturas e funciona com Celsius, Kelvin e Fahrenheit (mais comuns).

Algumas partes do código são gerados pela IDE que uso, NetBeans. No manual java possui um tutorial ensina a fazer um aplicativo que converte celsius para fahrenheit, fiz seguindo o tutorial. A parte das outras funções, não segui tutorial algum.
