Error when adding Big Decimal elements

Question

I need to add all pre-defined elements to the elements that will be inserted by the user, but gives error when instantiating Bigdecimal

private BigDecimal concentracaoK;
     
private BigDecimal concentracaoNa;
   
public Curva(Long id, Amostra amostra, BigDecimal concentracaoK, BigDecimal concentracaoNa) {

    this.id = 0L;
    this.amostra = amostra;
    this.concentracaoK =  new BigDecimal("0.00");
    this.concentracaoNa =  new BigDecimal("0.00");
    
}

CurvaRepositorio repoc = new CurvaDAO(0.0, 0.2, 0.4, 0.8, 1.2, 1.6);
