multithreading - Exception in thread "main" java.lang.IllegalMonitorStateException -


i working thread in java , following error - don't understand why?!

code:

import java.util.random;  public class test {       public static void main(string[] args) throws interruptedexception {      vlakno sude = new vlakno("myname"); // vlakno = thread class          sude.start();         sude.wait(); // error on line     }  }  class vlakno extends thread {      private boolean canirun = true;     private final string name;      vlakno(string name) {         this.name = name;     }      @override     public void run() {         while (canirun) {           //  system.out.println("name: " + name);         }     }      public void mojestop() {         system.out.println("thread "+name +" end...");         this.canirun = false;     } }

in order deal illegalmonitorstateexception must verify invokations of wait method taking place when calling thread owns appropriate monitor. simple solution enclose these calls inside synchronized blocks. synchronization object shall invoked in synchronized statement 1 monitor must acquired.

synchronize (sude) {   sude.wait(); }

for more informations , examples, take here.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
