multithreading - Removing idle threads from thread pool in Java? -

-

i'm using java thread pool of fixed size (executorservice). let's assume submit job thread pool , job gets idle.

is there possibility idle jobs removed thread pool, other jobs queue can processed , idle job later added again?

if move executorservice threadpoolexecutor, can achieve below api

public void setcorepoolsize(int corepoolsize)

sets core number of threads. overrides value set in constructor. if new value smaller current value, excess existing threads terminated when next become idle.

if larger, new threads will, if needed, started execute queued tasks.

if want re-size pool @ run time,

((threadpoolexecutor)service).setcorepoolsize(newlimit); //newlimit new size of pool

other api:

public void setmaximumpoolsize(int maximumpoolsize)

sets maximum allowed number of threads. overrides value set in constructor. if new value smaller current value, excess existing threads terminated when next become idle.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
