長類rotateRight()方法 (Long class rotateRight() method)

• rotateRight() method is available in java.lang package.

  rotationRight()方法在java.lang包中可用。

• rotateRight() method is used to returns the value generated by rotating the binary 2’s complement denotation of the given argument (value) right by the given number of bits.

  rotationRight()方法用于返回通過將給定參數(值)的二進制2的補碼符號向右旋轉給定位數而生成的值。

• rotateRight() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.

  rotationRight()方法是一個靜態方法，也可以使用類名進行訪問，如果嘗試使用類對象訪問該方法，那么也不會收到錯誤。

• rotateRight() method does not throw an exception at the time of rotating or shifting of bits.

  旋轉或移位位時， rotateRight()方法不會引發異常。

Syntax:

句法：

public static long rotateRight (long value, int rotation);

Parameter(s):

參數：

• long value – represents the long value to be parsed.

  long value –表示要解析的long值。

• int rotation – represents the distance of rotation.

  int rotation –表示旋轉距離。

Return value:

返回值：

The return type of this method is long, it returns a long value generated by rotating the 2’s complement binary of the given long value right by the given number of bits.

此方法的返回類型為long ，它返回通過將給定long值的2的補碼二進制數右移給定位數而生成的long值。

Example:

例：

// Java program to demonstrate the example // of rotateRight (long value, int rotation) method of Long classpublic class RotateRightOfLongClass {public static void main(String[] args) {long value = 3;int rotation = 1;// Iterates till the value of rotation reacheswhile (rotation < 4) {// It return the value generated by rotating the 2's// complement of the given argument (value) right // by the given number of bitsvalue = Long.rotateRight(value, 3);System.out.println("value: " + value);++rotation;}} }
