Java - Long rotateRight() method
Description
The Java Long rotateRight() method returns the value obtained by rotating the two's complement binary representation of the specified long value i right by the specified number of bits. (Bits shifted out of the right hand, or low-order, side reenter on the right, or high-order.)
Declaration
Following is the declaration for java.lang.Long.rotateRight() method
public static long rotateRight(long i, long distance)
Parameters
i − This is the long value.
distance − This is the rotation distance.
Return Value
This method returns the value obtained by rotating the two's complement binary representation of the specified long value right by the specified number of bits.
Exception
NA
Example 1
The following example shows the usage of Long rotateRight() method to get an long by rotating the two's complement binary representation of the specified long value i right by the specified number of bits. We've created a long variable and assigned it a positive long value. Then using rotateRight() method within a for loop, we're printing new integers generated.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long n = 2L; // returns the value obtained by rotating right for(long i = 0; i < 4; i++) { n = Long.rotateRight(n, 4); System.out.println(n); } } }
Output
Let us compile and run the above program, this will produce the following result −
2305843009213693952 144115188075855872 9007199254740992 562949953421312
Example 2
The following example shows the usage of Long rotateRight() method to get an long by rotating the two's complement binary representation of the specified long value i right by the specified number of bits. We've created a long variable and assigned it a negative long value. Then using rotateRight() method within a for loop, we're printing new integers generated.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long n = -2L; // returns the value obtained by rotating right for(long i = 0; i < 4; i++) { n = Long.rotateRight(n, 4); System.out.println(n); } } }
Output
Let us compile and run the above program, this will produce the following result −
-1152921504606846977 -72057594037927937 -4503599627370497 -281474976710657
Example 3
The following example shows the usage of Long rotateRight() method to get an long by rotating the two's complement binary representation of the specified long value i right by the specified number of bits. We've created a long variable and assigned it a zero value. Then using rotateRight() method within a for loop, we're printing new integers generated.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long n = 0L; // returns the value obtained by rotating right for(long i = 0; i < 4; i++) { n = Long.rotateRight(n, 4); System.out.println(n); } } }
Output
Let us compile and run the above program, this will produce the following result −
