}O jeito mais fácil, creio eu, é utilizar um contador, e você pode fazer esse contador da própria JLabel onde está mostrando o número de ingressos. A lógica é simples.
Veja bem, sempre que ele clicar em uma poltrona, você captura o valor da JLabel que mostra a quantidade, aumenta um e troca o valor.
// clicou na poltrona
if (e.getSource() == b5) {
b5.setBackground(Color.red);
b5.setEnabled(false);
b5.setText("OCUPADO");
// aqui você faz a lógica para aumentar a quantidade de ingressos mostrados na label
int qtde = Integer.parseInt(jlabel.getText()); // captura o valor e converte para inteiro
qtde++; // incrementa 1 na quantidade
jlabel.setText(String.valueOf(qtde)); // atualiza a label (lembre-se de converter para String utilizando o método String.valueOf()
}
É basicamente isso.
