How can I change this. & total = 10 & date = 2018-03-02 & idAgR = 1 . to
& total = 10 & date = 201/03/02 & ampAgR = 1 . ? since I make a direct request either Chrome or Firefox 
since you mark me an error in this method
public String RegGiro (Sender rm, Recipient rc, Items it, int idAgR, Giro gr) {...}
with which I should change this 2018-03-02 to 2018/03/02 in the URL
public class Items implements java.io.Serializable {
private Integer idItem;
private BigDecimal monto;
private BigDecimal igv;
private BigDecimal total;
private BigDecimal comision;
private Date fecha;
}
