Java provides two primitive types that we can use for storing decimal numbers:floatanddouble.Doubleis the default type: double PI = 3.1415; However, weshould never use either type for precise values, such as currencies. For that, and also for rounding, we can use theBigDecimalclass. 3. For...
There are examples of immutable built-in Java classes such as the primitive wrapper classes (Byte, Short, Integer, Long, Float, Double, Character, and Boolean), and BigInteger and BigDecimal. Rules to create immutable class: In order to make a Java class immutable, follow these rules. ...
Java has a BigDecimal class that represents decimal numbers up to a large number of precision digits. This class of java also has some set of functionalities that are not available in the primitive data types, for example, integer, doubles, and floats. These functionalities provide rounding off ...
You can write custom exception classes that inherit fromjava.lang.Exceptionso they are checked by the compiler, orjava.lang.RuntimeExceptionif you want your custom exception to be unchecked. Most often, though, custom exception classes will be checked and will inheritjava.lang.Exception. ...

4. Second Approach: Using BigDecimal The BigDecimal class in Java provides its user with complete control over rounding behavior. This class also provides operations for arithmetic, scale manipulation, rounding, comparison, hashing, and format conversion. Let’s use BigDecimal to get the int...
When doing currency calculations in Java, you might use java.math.BigDecimal—but beware of some of that class’s unique challenges.
