Java 物件概要

Java 類別的形成：

public class Shirt{

 public int shirtID = 0;
 public String description = "-----";
 public char colorCode = 'U' ; //R=red,G=green,B=blue,W=white
 public double price = 0.0;
 
 //顯示 Shirt 相關資料
 public void displayInformation(){
 
  System.out.println("Shirt ID: " +  shirtID);
  System.out.println("Description: " + description);
  System.out.println("Shirt Color: " + colorCode);
  System.out.println("Shirt's price: " + price);
 }
}

Java 物件的利用：

public class Demo{

 public static void main(String[] args){
 
  Shirt myShirt = new Shirt();
  myShirt.displayInformation();
 
 }
}
