BigDecimal in Java

To create a BigDecimal object in Java, you call one of the constructors you see below. Each of these constructors takes a value and converts it to a BigDecimal object.

BigDecimal is a class that belongs to java.math package. We use float and double primitive data types for decimal numbers but there is one problem with these primitive types. Float and double that these types should never be used for precise value, such as currency.

BigDecimal value = new BigDecimal(0.01);
System.out.println(value);
