A few days ago wrote a small program, run the time found in the loop the second time there is a java.lang.IllegalThreadStateException exceptionThrough the Internet query found that the same thread can not repeatedly call the Start method, make the following changes:Change your defined Sellticket extends thread class to Sellticket implements Runnable, and then use

We are going to start a thread, which is to call the start method of a thread instance. Let's take a look at the source of the Start method:1 Public synchronized voidstart () {2 3 //A value of 0 means that the thread is newly st

I recently saw a question with the following code: = "Ping" "pong" Q: What Will be output? I run it many times and the result is pong ping. Later, the key point was found. The thread object t called not the start () method, but the run () method. Later, I opened the breakpoint mode debug and found that the entire program has only one thread to call the run ()

When a new thread starts, it will execute this function without any parameters, if there is no return value, how can we call a function with parameters? The previous section uses constructors to pass parameters. This section uses other method
