i know bit naive question want understand basic working principle behind multi-threading in java. consider following code , executed in main thread , starts execution of worker thread ,defined in class b. want know can b.func1 called , run method of b, executed in parallel or not?
public class { public static void main(string[] args) { b obj = new b(); obj.start(); obj.func1(); } } public class b extends thread { public b() { //constructor } public void run() { while(true) { //do somethings } } public void func1() { //do someotherthings } }
there no magic behind method call. if call method thread, called in same thread. since obj.func1() called main, run in main thread. doesn't matter class belongs or whether or not extends thread.
the new thread starts executing run. called run , on executed in parallel main.
