设计模式实验三(3)

public interface SkinFactory { } SpringSkinFactory.java public class SpringSkinFactory implements SkinFactory { } SummerSkinFactory.java public class SummerSkinFactory implements SkinFactory { public AbstractButton createButton() { } public AbstractTextbox createTextbox() { } public AbstractComboBox createComboBox() { System.out.println(\生产 blue combo box\return new BlueComboBox(); System.out.println(\生产 blue textbox\return new BlueTextbox(); System.out.println(\生产 blue button\return new BlueButton(); public AbstractButton createButton() { } public AbstractTextbox createTextbox() { } public AbstractComboBox createComboBox() { } System.out.println(\生产green combo box\return new GreenComboBox(); System.out.println(\生产green textbox\return new GreenTextbox(); System.out.println(\生产green button\return new GreenButton(); public AbstractButton createButton(); public AbstractTextbox createTextbox(); public AbstractComboBox createComboBox(); 11

} } Client.java public class Client { public static void main(String args[]){ } }

实现代码： public class Compute { private static Compute[] instance; private Compute() { } public static Compute getInstance(int number) { if(number <= 0) System.out.println(\请输入大于0的整数\ if(instance.length == 0){ for(int i = 0, i < number, i++){ Instance[i]=new Singleton(); } } int x = (int)(Math.random() * number); Int y = x + 1; System.out.println(\调用第y台电脑\

return instance[x]; 12

} }
