[Solved] Java – Thread.join( ) does not release the lock

by

That’s because Thread.join() doesn’t release any locks. You’ve designed a perfectly working deadlock, where Thread-1 is waiting for Thread-2 to die having locked on Foo, and Thread-2 is waiting to lock on Foo. (Technically speaking the current implementation does release locks, as it uses internally wait() while synchronized on Thread. However that’s an internal mechanism … Read more

[Solved] two jquery sliders having same class name but the issue is on moving the slider

by

Your code in the slider’s slide function calls $( “.slider-value”).html( ui.value );. This, as you can see, is changing the inner HTML of all elements with the class .slider-value.

[Solved] char () and int () are functions in c++? [duplicate]

by

They’re not functions. They’re just alternate syntax for type-casting. char(x) is more-or-less equivalent to static_cast<char>(x). In general, in C++, one should prefer the C++-specific constructs for casting objects (static_cast, dynamic_cast, const_cast, and reinterpret_cast), as those help ensure you don’t do anything dumb when casting objects. So in your code example, I’d recommend rewriting it as … Read more
