Usage of @AliasFor

In Spring's many annotations, it is often found that many different attributes of different annotations play the same role, such as @RequestMapping's value attribute and path attribute. In order to keep their behavior consistent, such as the value of value and the value of path can not conflict, their values should always be equal. To handle these issues uniformly, Spring created the @AliasFor tag.

The @AliasFor tag has the following usage methods.

1, explicit use within the same annotation

For example, the usage in @RequestMapping:

package com.algorithm.bitwise;

import java.util.List;
import java.util.concurrent.atomic.AtomicInteger;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class FindLargestElementV2 {
	//MSB: most significant bit.
	public static long countGreaterOrEqualElementWithSameMSB(List<Integer> seq, int valueAtMSBIndex) {

logbasex

public static int getLargerNumber(int a, int b) {
		int c = a - b;
		//get sign bit's value
		int k = (c >> 31) & 0x1;
		return a - k * c;
	}
	
	public static void main(String[] args) {

FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.
