Olá pessoal estou fazendo um conversor de base que de acordo com que o usuário vai digitando ele vai convertendo, mas o problema que o evento KeyPressed está atrasado. EX: se eu abro o programa e digito 1 em decimal ele não faz nada nos outros Text Fields. Se eu pressionar um novo numero ele mostra o que ele deveria ter mostrado antes, e assim por diante, ou seja, ele fica sempre atrasado um numero.
Como eu resolvo isso?
Obrigado.

while (dec > 0) {
result = (dec & 1) + result;
dec >>= 1;
}
return result;
}
private int binaryToDec( String bin ) {
int i, result = 0;
for( i = 0; i < bin.length(); i++ ) {
result <<= 1;
if( bin.charAt( (int) i) == '1' ) result++;
}
return result;
