java - How Can I iterate this map in reverse direction -


this map iterators remove data based on conditions, want run same map in reverse direction , conditions accordingly.

but couldn't find listiterator go easily.

how can go ?

also map implementation using treemap 

for(int i=countiteration;i<(countiteration+2);i++) {     iterator = imagefilexxsm.entryset().iterator();     while (it.hasnext()) {         map.entry pairs = (map.entry)it.next();         if(pairs.getkey().equals(data1.get(i).replace(".png", ".mp3")))           {             it.remove();         }     }      iterator itr = imagefilexxs.entryset().iterator();     while (itr.hasnext()) {         map.entry pairsx = (map.entry)itr.next();         if(pairsx.getkey().equals(data1.get(i)))              {             system.out.println("entry deleted."+pairsx.getkey());             itr.remove();         }     } }

treemap has descendingmap method (note returns view on original map, not copy it):

//iterate on entry set in reverse order (map.entry<x,y> e : map.descendingmap().entryset()) {     x key = e.getkey();     y value = e.getvalue(); }

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
