This might help you What is making this code so slow is the many calls to Calendar.getInstance(), creating Calendar objects. The code would already be a lot faster if you called this once per compare.
However, it doesn't make much sense to keep creating these in a single sort run. You can either set a static Calendar reference that the sort can use, or use System.currentTimeMillis to get the current time.

How can I sort a List several different ways in a JSP?


Tag : java , By : user167963

it should still fix some issue The SO EL Tag Wiki describes a way to do this without using a scriptlet: using an EL function to do the sort, then using the result for the items attribute in the JSTL core forEach tag.
The function class:
package org.hierax.ifdl.tags.player;

public final class PlayerSort {
    public static List<Player> sortByRank(List<Player> playerList) {
        Collections.sort(playerList, new PlayerSortByRank());
        return playerList;
    }

    public static List<Player> sortByAlias(List<Player> playerList) {
        Collections.sort(playerList, new PlayerSortByAlias());
        return playerList;
    }
}

Differents authentication ways on same URLs with spring-boot


Tag : java , By : Anthony Eden

wish help you to fix your issue Finally I got a solution to this problem so I will briefly share it :
So we have multiple Authentication ways, described in several classes extending AbstractPreAuthenticatedProcessingFilter. (all those will not be added to the filter chain)
http.addFilterBefore(new MultiAuthModeSecurityFilter(
                FirstSecurityFilter(),
                SecondSecurityFilter(),
                ThirdSecurityFilter()), RequestCacheAwareFilter.class);
    @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            /*some actions to define the right authMethod to use*/
            switch (authMethod) {
                case FIRST:
                    firstFilter.doFilter(servletRequest, servletResponse, filterChain);
                    break;
                case SECOND:
                    secondFilter.doFilter(servletRequest, servletResponse, filterChain);
                    break;
                case THIRD:
                    thirdFilter.doFilter(servletRequest, servletResponse, filterChain);
                    break;
                default:
                    /* throws exception */ break;
            }
        }

Sort the list in two different ways, one after the other


Tag : java , By : toki

I wish this help you Simply you can try removing and adding element back to the list.
it will push element to the end of the list and there is no need of while loop:
int k = 0;
for (i = 0; i < array.size()-k; i++) {
            if (array.get(i).isConsumido()) {
                ItemCultural item = array.remove(i);
                array.add(item);
                k++;
                i--;
            }
}

python how to sort differents lists with a single unique value and append it to a result list


Tag : python , By : Robert M
Date : March 29 2020, 07:55 AM
around this issue If you want to learn about merge sort, here is how merge sort can be written in python which is implemented using recursive functions and what it does is split the list into two sublists, sort each one separately and than combine them together while maintaining the order:
def combine(left, right):
    if(len(left) == 0):
        return(right)
    elif(len(right) == 0):
        return(left)
    else:
        if(left[0] <= right[0]):
            return([left[0]] + combine(left[1:], right))
        else:
            return([right[0]] + combine(left, right[1:]))

def msort(myList):
    if(len(myList) == 0 or len(myList) == 1):
        return myList
    splitInd = len(myList)/2
    left = myList[:splitInd]
    right = myList[splitInd:]
    return(combine(msort(left), msort(right)))
l = [5,2,3,4,1,6,7]
msort(l)
# [1, 2, 3, 4, 5, 6, 7]

plpgpsql - differents forms of temporary table in order to do a sort


Tag : postgresql , By : stu73
Date : March 29 2020, 07:55 AM
it should still fix some issue I'm trying to optimize a function that has 7 WITH temporary tables, acting as sort mechanisms, cascading from the initial temporary table/sort to the next one until the last one e.g the 7th temporary table/ sort. , there is nothing wrong with using create temporary table in function:
t=# create or replace function so37() returns table (i int) as
$$
declare
begin
create temporary table a as select 2;
return query select * from a;
end;
$$ language plpgsql
;
CREATE FUNCTION
t=# select * from so37();
 i
---
 2
(1 row)
t=# select * from so37();
ERROR:  relation "a" already exists
CONTEXT:  SQL statement "create temporary table a as select 2"
PL/pgSQL function so37() line 4 at SQL statement
