Answer 1

Change your variable pressing to private, then you can make a method that returns the value of pressing. Then move the method call to just before the if statement or use it as the condition for the statement.

In W class

private static boolean pressing = false;

public boolean isPressing() {
return pressing;
}

In main

var walking = walk.isPressing();
if(walking) {
...
...

Or delete walking variable and use

if(walk.isPressing()) {
...
...

Answer 2

var walking = walk.pressing; // false

In your conditions for if and while you probably want walk.pressing but if you do so then you will have an infinite loop. It will run in the playground until it times out and then will print all the output.
