I have the following method:
public String insereRegistro(int tipo, String data, String horario, String historico,
int veiculo, double km, int cliente, int solicitante,
String finalizado) {
...
}
How do I get the method to accept the null value?
You can pass null on all parameters other than primitive types.
If you want to do the same for parameters of the primitive type replace them with the respective classes:
public String insereRegistro(Integer tipo, String data, String horario, String historico,
Integer veiculo, Double km, Integer cliente, Integer solicitante,
String finalizado) {
...
}
