double distance = calculateDistance(x1, y1, x2, y2); System.out.println("The distance between the two points is: " + distance); }。 }。 在上面的例子中,我们使用了Math.sqrt和Math.pow来计算两点之间的距离。这个方法可以很容易地扩展到三维空间中,只需要增加z坐标的计算。 另外,Java也提供了Point...
ADurationrepresents a directed distance between two points on the time-line and can therefore be positive, zero or negative. This method checks whether the length is zero. Returns: true if this duration has a total length equal to zero ...
* @return an array of two GeoLocation objects such that: * The latitude of any point within the specified distance is greater * or equal to the latitude of the first array element and smaller or * equal to the latitude of the second array element. * If the longitude of the first ...
distanceSq public static double distanceSq(double x1, double y1, double x2, double y2) Returns the square of the distance between two points. Parameters: x1- the X coordinate of the first specified point y1- the Y coordinate of the first specified point ...

(especially global optimizations such as inlining) are much harder to perform for method invocations. Many traditional optimizations are most effective between calls, and the decreased distance between calls in the Java language can significantly reduce the effectiveness of such optimizations, since they ...
