// Primitive types: int, double, boolean, char, float, byte, short, long
// JFrame: a window
// Need to specify that we want to use JFrame:
import javax.swing.JFrame;
JFrame j1 = new JFrame();
j1.show();
// show() is a method call
// instruction: an action to be perform, like "add 7 + 8"
// Java statement: an instruction written using the Java language
// Java program: an organized collection of Java statements
// execute: to follow the instructions
j1.setTitle("This is the title.");
j1.getX()
// There are 3 different types of methods:
// functions, procedures, constructors
// functions return data of a particular type
// procedures perform a set of actions
j1.getY()
j1.hide()
j1.getY()
j1.show()
j1.Show()
// . is a binary operator that works with class variables (e.g., j1) and methods (e.g., show()).
