方法详细资料

plus

public static Object plus(Object number,
                          int augend)
                   throws ArithmeticException

Returns a number Object whose value is (number + augend), Note: This method will throw ArithmeticException if number overflows.

抛出:

ArithmeticException

minus

public static BigDecimal minus(Object minuend,
                               Object subtrahend)

Returns the difference BigDecimal whose value is (minuend - subtrahend).

compare

public static int compare(Object obj1,
                          Object obj2)

Compares two comparable objects.

返回:

The value 0 if num1 is equal to the num2; a value less than 0 if the num1 is numerically less than the num2; and a value greater than 0 if the num1 is numerically greater than the num2.

抛出:

ClassCastException - if the compared objects are not instance of Comparable or not mutually comparable (for example, strings and integers).

doubleCompare

public static int doubleCompare(double arg1,
                                double arg2)

Compares two Double numeric object.

返回:

-1, 0, or 1 as this arg1 is numerically less than, equal to, or greater than arg2.
