Why does Java allow to assign a string literal to a String object? -


string class in java. while declaring , assigning string, correct string name = "paul" though instantiate object java class string name = new string(); taking name object, i'm wondering why can assign series of characters "paul" object. under concept 1 works , how it?

that's because implicitly strings - "..." treated objects well.

under cover jvm looks similar "objects" in called string pool , if finds there returns object (instead of creating new one) otherwise creates new object , puts string pool.

this memory efficiency, , "paul" new string("paul") not same.

this possible because know, strings immutable in java.

you can read more behavior search keyword "string pool".

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
