我刚刚开始使用windowbuilder来学习Java的GUI，当这些问题发生时，我感到很茫然......还有更好的可视化工具来学习Java的GUI吗？
Here is the code:
import java.awt.Color;

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable()

try
{
Calculator window = new Calculator();
window.frame.setVisible(true);
} catch (Exception e)
{
e.printStackTrace();
}
}
});
}
/**

public Calculator() {
initialize();
}
/**

System.exit(0);

putValue(SHORT_DESCRIPTION, "Some short description");
}
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
}
}
例外可以列举如下，我想知道我的代码发生了什么，为什么windowbuilder提供的代码有这些问题..

答案 0 :(得分：1)
"id"["uri"]的行for会引发错误，因为您尝试仅使用4个元素访问数组的第5个元素。
请注意，perfis = {}
for chave, valor in deputados.items():
print(valor)
print(chave)
resposta = requests.get(valor)
answer = resposta.json()
perfis.setdefault(chave, {})['uri'] = answer['dados']['uri']
perfis.setdefault(chave, {})['nomeCivil'] = answer['dados']['nomeCivil']
perfis.setdefault(chave, {})['nomeEleitoral'] = answer['dadultimoStatusos']['nomeEleitoral']
perfis.setdefault(chave, {})['siglaPartido'] = answer['dadultimoStatusos']['siglaPartido']
perfis.setdefault(chave, {})['siglaUf'] = answer['dadultimoStatusos']['siglaUf']
perfis.setdefault(chave, {})['urlFoto'] = answer['dadultimoStatusos']['urlFoto']
perfis.setdefault(chave, {})['telefone'] = answer['ultimoStatus/gabinete']['telefone']
perfis.setdefault(chave, {})['email'] = answer['ultimoStatus/gabinete']['email']
perfis.setdefault(chave, {})['sexo'] = answer['ultimoStatus/gabinete']['sexo']
perfis.setdefault(chave, {})['dataNascimento'] = answer['ultimoStatus/gabinete']['dataNascimento']
始终为0。因此，最大可访问元素为3（comboBox.setSelectedIndex(4);）
