10. Java Class Example package example; import java.awt.Point; public class Rectangle { privateint width = 0; privateint height = 0; private Point origin; public Rectangle() { origin = new Point(0, 0); } public Rectangle(int w, int h) { this(new Point(0, 0), w, h); } public Rectangle(Point p, int w, int h) { origin = p; width = w; height = h; } publicvoid setWidth(int width) { this.width = width; } } data members constructors a method

11. Running Java Programs packagemp; // file mp/HelloWorld.java public classHelloWorld { public staticvoid main(String[] args) { System.out.println(“Hello World !”); } } > javac HelloWorld.java The compilation phase: This command will produce the java bytecode file HelloWord.class > java –cp . HelloWorld The execution phase (on the JVM): This command will produce the output “Hello World!”
