Galera alguem por favor poderia me dizer como faço pra formatar um byte em string.
Estou lendo dados de uma balaça, e os dados via Hyper Terminal vem assim:
-
112 g ...
Na minha aplicação leio os dados e ele vem assim:
-
1
12 g
Ou seja fiz um display para interfacear com o usuário do que so aparece o 12g sendo que são 112g.
Ja fiz de tudo que imaginei e pensei …
segue o codigo:

Nada mais eh que o SimpleRead da Sun.
