Rounding mode with BigDecimal in Java

The following code, which uses RoundingMode.HALF_EVEN,

BigDecimal value1 = new BigDecimal("4.5");
value1=value1.setScale(0, RoundingMode.HALF_EVEN);

BigDecimal value2 = new BigDecimal("6.5");
value2=value2.setScale(0, RoundingMode.HALF_EVEN);

System.out.println(value1+"\n"+value2);

displays 4and 6accordingly. I think that it should display 5and 7accordingly, because the figure on the left of the discarded fractional part (which in this case is equal to 5) is odd . In this case, it performsRoundingMode.HALF_UP

And in the case RoundingMode.HALF_UP, it RoundingMode.UPis executed when the discarded fractional part is> = 0.5 (this is true), otherwise it is executed RoundingMode.DOWN.
