长类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()方法用于返回通过将给定参数(值)的二进制2的补码符号向右旋转给定位数而生成的值。

• 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()方法是一个静态方法，也可以使用类名进行访问，如果尝试使用类对象访问该方法，那么也不会收到错误。

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

  旋转或移位位时， rotateRight()方法不会引发异常。

Syntax:

句法：

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

Parameter(s):

参数：

• 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 –表示旋转距离。

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.

此方法的返回类型为long ，它返回通过将给定long值的2的补码二进制数右移给定位数而生成的long值。

Example:

例：

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