Java For Testers No, constructor does not return any value. While declaring a constructor you will not have anything like return type. In general, Constructor is implicitly called at the time of instantiation. And it is not a method, its sole purpose is to initialize the instance variables.
If we add a return type to a constructor, then it will become a method of the class. This is the way java runtime distinguish between a normal method and a constructor.
No, constructor does not have any return type in Java. Constructor looks like method but it is not. It does not have a return type and its name is same as the class name.
Is it possible for a constructor to be pre-empted in C#?
For example, consider the code:
public class A
{
public bool ready = true;
public A()
{
ready = false; // Point #1
// Other initialization stuff
ready = true; // Point #2
}
}
Somewhere else in the code two threads have access to a variable of type A, the first thread calls the constructor which is pre-empted at point #1. Then the second thread tests for ready and finds it to still be true therefore it does something bad.
Is this scenario possible?
