Java BigDecimal how to format

Code:

     BigDecimal bd = new BigDecimal(1.0);

>>> alexey: Asd.main bd.toPlainString() = 1
>>> #0.0## -> 1.0

ORrrrr:

Code:

     BigDecimal bd = new BigDecimal("1.0");
    
     System.out.println(">>> alexey: Asd.main bd.toPlainString() = " + bd.toPlainString());

Result:

>>> alexey: Asd.main bd.toPlainString() = 1.0
