olá,
Fiz um programa e estou com problemas.
Seguinte, eu compilo o programa pelo jcreator e não aparece o resultado esperado, mas se ficar executando várias vezes ele vai mudando o resultado sem eu alterar o código. Não tenho nem ideia do que pode ser, será q alguem poderia me ajudar.
Se eu ficar executando várias vezes, uma hora eu chego no resultado esperado, mas não roda de primeira.
segue o código:

import java.awt.*;
