Some important pointers for this exam
When using BigDecimal, it is important to note the following:
• Use the constructor with the String argument as it does a better job at
placing the decimal point
• BigDecimal is immutable
• The ROUND_HALF_EVEN rounding mode introduces the least bias
Objects of these wrapper classes are immutable. That is, their values cannot
be changed.
