How does I/O-methods like read() put a Thread in blocked state in java?

问题 So, if i have understood this correctly, a thread goes into waiting state when we call wait on an object and it goes into blocked state when it is waiting for a lock on an object(like when trying to get into a synchronized block or method). How does I/O-methods like read() put a Thread in a blocked state though? I understand WHY it has to be in a blocked state, waiting for data that it can read but i'm also interested in HOW. How does the JVM notify the thread that it can continue when data

问题 Off late i am working on multithreading in java. Want to understand if a Thread is in BLOCKED state why it cant be interrupted? And why the thread can be interrupted only if it is in WAIT state?

This question might be very basic but, I am trying to understand things rather than just remembering them. 回答1: One assumes that you mean cause the thread to stop its current operation and

问题 I am working for my network class at a chatroom application, in java, and i have encountered some issues with the connection. The main problem is that I can connect my client to the server, however when I'm trying to use my external ip is not working.So i browsed the web and i found that I have to port forward from my router in order to accept the connection from an external ip. I've done that, but I didn't work. After I searched for an answer I found that the connection somehow is blocked,

Site URL blocked as “Spammy”, but also no data was scraped in debug

问题 Made a website for a client of mine who owns a small business. About three months ago, her site URL was blocked by Facebook for being "Spammy". We launched a pretty impressive "Go Here And Report It As Safe" campaign, but alas, it's not unblocked. We made a new domain that mirrored the blocked one. This worked for about an hour. Then lo and behold! It got blocked too. I was very curious, so I decided to try out the "Object Debugger". When I did, I got this message: "Error Parsing URL: Error
