é o seguinte, to desenvolvendo um software, minha ideia é fazer com que o usuário selecione um município, e em seguida seja mostrado em um jPanel.
eu criei um método para mostra o município, esse método recebe uma string nome, que é o nome município como parâmeto, ai eu ja inicio a aplicação com um município pré-estabelecido.
Só que eu quero mudar a String nome do método a partir de um click no botão, porém não consigo de jeito nenhum ter acesso ao public Principal2{ } para mudar o nome…
