Compare if BigDecimal is greater than zero

问题

How can I compare if BigDecimal value is greater than zero?

回答1:

It's as simple as:

if (value.compareTo(BigDecimal.ZERO) > 0)

The documentation for compareTo actually specifies that it will return -1, 0 or 1, but the more general Comparable<T>.compareTo method only guarantees less than zero, zero, or greater than zero for the appropriate three cases - so I typically just stick to that comparison.

回答2:

Possible better way:

if (value.signum() > 0)

回答3:

Use compareTo() function that's built into the class.

回答4:

using ".intValue()" on BigDecimal object is not right when you want to check if its grater than zero. The only option left is ".compareTo()" method.

回答5:

 BigDecimal obj = new BigDecimal("100");
 if(obj.intValue()>0)
    System.out.println("yes");
