Multiplying a variable with a value and assigning the value back to the variable is a common math operation in Java applications. Therefore Java contains an explicit operator for this operation. The *= operator. Here is first how the calculation would look without the *= operator: int result...
Returns the unbiased exponent used in the representation of a float. static double hypot(double x, double y) Returns sqrt(x2 +y2) without intermediate overflow or underflow. static double IEEEremainder(double f1, double f2) Computes the remainder operation on two arguments as prescribed by th...

java.lang.Number 抽象类,Java 中所有的数值类都继承它。 包装类(Byte、Short、Integer、Long、Float、Double)都是抽象类 Number 的子类。 Integer x = 5; x = x + 10; 1. 2. 当x 被赋为整型值时,编译器要对 x 进行装箱。为了使 x 能进行加运算,要对 x 进行拆箱。
