The difference between threadlocal and inheritablethreadlocal

ThreadLocal: Binds only to the current thread

Inheritablethreadlocal: Passes the value to the child thread and shares the value with the child thread

Use threadlocal, between parent and child threads, do not share value

Final threadlocal<string> tl = new threadlocal<string> ();

Tl.set ("Threadlocal-val");

System.out.println ("Main-1:" + tl.get ());

New Thread () {

public void Run () {

System.out.println ("Child-1:" + tl.get ());

};

}.start ();

Using inheritablethreadlocal, parent thread value allows child threads to share

Final threadlocal<string> ITL = new inheritablethreadlocal<string> ();

Itl.set ("Inheritablethreadlocal-val");

System.out.println ("Main-2:" + itl.get ());

New Thread () {

public void Run () {

System.out.println ("Child-2:" + itl.get ());

};

}.start ();
