Number类提供了将各种数字类型(如整数、浮点数等)转换为标准格式的方法(如intValue()、doubleValue()),并可以进行数字之间的转换和比较。 举个例子: import java.util.ArrayList;import java.util.List;public class ice {public static void main(String[] args) {// 创建一个List来存储不同类型的数值List num...

Returns the arc sine of a value; the returned angle is in the range -pi/2 through pi/2. Special cases: If the argument is NaN or its absolute value is greater than 1, then the result is NaN. If the argument is zero, then the result is a zero with the same sign as the argu...
Math类是Java中的一个final类,即无法被继承。它的源代码如下: 代码语言:java AI代码解释 publicfinalclassMath{// 省略部分代码/** * Returns the trigonometric sine of an angle. * * @param a an angle, in radians. * @return the sine of the argument. ...
