There probably is a very easy answer to this question but however I just don't get this because I just recently learned java. Take this simple code for example:
public class Test4 extends JFrame implements KeyListener {
public Test4(){
super("Test");
setSize(10,10);
addKeyListener(this);
setVisible(true);
}
static boolean test = true;
public static void main(String[] args){
Test4 frame = new Test4();
while(test){
//When I put a System.out.println statement here it will print Testing or some other statement otherwise it will not print Testing.
}
System.out.println("Testing");
}
public void keyPressed(KeyEvent arg0) {
int pressed = arg0.getKeyCode();
if(pressed == 87){//w key
test = false;
}
}
Here is the problem I am having trouble with, without a statement in the while loop it will not print Testing when test = false, but with a statement it will go through the while loop and wait until test = false and then it will print Testing. Basically what this test program is trying to do is wait until you press the w key and then it will print out Testing but the while loop will only wait for the key to be pressed if there is a statement within it...I hope that made any sense. I know there are many other more efficient ways to make a program wait till a key is updated but this is just a test to see if a while loop works without any statements and currently it doesn't work unless there are statements I just want to know why. Thanks.
