Screen类

• 获取全部屏幕宽高和坐标

  Rectangle2D rec = screen.getBounds();  
  System.out.println("left up x: " + rec.getMinX());  
  System.out.println("left up y: " + rec.getMinY());  
  System.out.println("right down x: " + rec.getMaxX());  
  System.out.println("right down y: " + rec.getMaxY());  
  System.out.println("width: " + rec.getWidth());  
  System.out.println("height: " + rec.getHeight());
  

  left up x: 0.0
  left up y: 0.0
  right down x: 1920.0
  right down y: 1080.0
  width: 1920.0
  height: 1080.0

• 获取可以看到屏幕宽高和坐标

  Rectangle2D rec2 = screen.getVisualBounds();  
  System.out.println("left up x: " + rec2.getMinX());  
  System.out.println("left up y: " + rec2.getMinY());  
  System.out.println("right down x: " + rec2.getMaxX());  
  System.out.println("right down y: " + rec2.getMaxY());  
  System.out.println("width: " + rec2.getWidth());  
  System.out.println("height: " + rec2.getHeight());
  

  left up x: 0.0
  left up y: 0.0
  right down x: 1920.0
  right down y: 1042.0
  width: 1920.0
  height: 1042.0
