# 'compare()' method can be used to compare numbers

Reports expressions that can be replaced by a call to the `Integer.compare()`

method or a similar method from the `Long`

, `Short`

, `Byte`

, `Double`

or `Float`

classes, instead of more verbose or less efficient constructs.

If `x`

and `y`

are boxed integers, then `x.compareTo(y)`

is suggested, if they are primitives `Integer.compare(x, y)`

is suggested.

**Example:**

Note that `Double.compare`

and `Float.compare`

slightly change the code semantics. In particular, they make `-0.0`

and `0.0`

distinguishable (`Double.compare(-0.0, 0.0)`

yields -1). Also, they consistently process `NaN`

value. In most of the cases, this semantics change actually improves the code. Use the checkbox to disable this inspection for floating point numbers if semantics change is unacceptable in your case.
