Java NetBeans GUI Key Event sending -


i'm making simple calculator, far did text field can type numbers , listens if key typed keyboard.

private void resultkeytyped(java.awt.event.keyevent evt) {  }

what want click on let's '1' mouse , send key event method, clicked on keyboard. tried doing keypress robot says 'void type no here' or that. wanted run resultkeytyped method withing mouse click listener, this:

private void jbutton1mouseclicked(java.awt.event.mouseevent evt)  {     resultkeytyped(keyevent.vk_1); }

to call resultkeytyped, have pass keyevent. can create keyevent using appropriate constructor: 

keyevent event = new keyevent(textfield, 0, system.currenttimemillis(), 0, keyevent.vk_1); resultkeytypes(event);

although description (eg simple calculator), sounds may wish choose different approach:

  1. add actionlistener jbutton
  2. within implementation of actionlistener, change jtextfield text using settext method

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.
