Park after executing interrupted () () failure-CodePudding

To perform first interrupted () method can get the expected results, thread interrupt tag is empty, park () can normal blocking threads

 private static void test4 () {
Thread the t1=new Thread (() - & gt; {
for (int i=0; I & lt; 5; I++) {
The debug (" park... "); 
LockSupport. Park (); 
Log. The debug (" interrupt status: {} ", Thread interrupted ()); 
Log. The debug (" interrupt status: {} ", Thread currentThread (). The isInterrupted ()); 
} 
}); 
T1. Start (); 


Sleep (1); 
T1 interrupt (); 
}

The results

 14:59:59. 983 c.T estInterrupt [Thread - 0] - park... 
15:00:00. 982 c.T estInterrupt [Thread - 0] - interrupt status: true 
15:00:00. 983 c.T estInterrupt [Thread - 0] - interrupt status: false 
15:00:00. 983 c.T estInterrupt [Thread - 0] - park...

If it is to run the isInterrupted () method, then the park () until the next interrupted () will block the thread when

 private static void test4 () {
Thread the t1=new Thread (() - & gt; {
for (int i=0; I & lt; 5; I++) {
The debug (" park... "); 
LockSupport. Park (); 
Log. The debug (" interrupt status: {} ", Thread currentThread (). The isInterrupted ()); 
Log. The debug (" interrupt status: {} ", Thread interrupted ()); 
} 
}); 
T1. Start (); 


Sleep (1); 
T1 interrupt (); 
}

The results

 15:05:34. 855 c.T estInterrupt [Thread - 0] - park... 
15:05:35. 853 c.T estInterrupt [Thread - 0] - interrupt status: true 
15:05:35. 854 c.T estInterrupt [Thread - 0] - interrupt status: true
