My Eclipse shows error in act asking it to be used as a local variable but in code provided by you its nothing like that . Later also when i fix this code seems not be working in vertical and horizontal scrolling . Please provide solution or any working code .

Dimension dim = driver.manage().window().getSize();
int width = dim.width;
int height = dim.height;
System.out.println("Width - "+ width);
System.out.println("Height - "+ height);
int middleX = width/2;
int startY = (int)(height * .8);
int endY = (int)(height * .2);
act
.press(PointOption.point(middleX,startY))
.waitAction(WaitOptions.waitOptions(Duration.ofMillis(3)))
.moveTo(PointOption.point(middleX,endY))
.release()
.perform();
