Answer 1

draw on a JPanel https://docs.oracle.com/javase/8/docs/api/javax/swing/JPanel.html

with Graphics2D https://docs.oracle.com/javase/8/docs/api/java/awt/Graphics2D.html

You can also use Canvas and Graphics, but they are older APIs.

Answer 2

My recommendation is to use the java.awt and javax.swing APIs. Using things like graphics/graphics2D(this one has more options) and a JFrame and JPanel. There are plenty of good tutorials on YouTube.
