In Java, you can determine if a BigDecimal object is null using the equals() method or the “==” operator.

  1. Utilize the equals() method:
BigDecimal decimal = null;
if(decimal == null) {
    System.out.println("BigDecimal对象为空");
}
  1. Using the “==” operator:
BigDecimal decimal = null;
if(decimal.equals(null)) {
    System.out.println("BigDecimal对象为空");
}

Both methods can correctly determine if a BigDecimal object is empty. It is important to note that when using the equals() method, a null should be passed as a parameter to the method.
