模版设计模式

1、提高代码的重用性

package TemplateTest;

public abstract class TemplateSource {

	public abstract void compataOperation1();

	public abstract void compataOperation2();

	public void template() {
		System.out.println("start");
		compataOperation1();
		compataOperation2();
		System.out.println("end");
	}

}

 

package TemplateTest;

public class TemplateA extends TemplateSource {

	@Override
	public void compataOperation1() {
		System.out.println("operation A mothod");
	}

	@Override
	public void compataOperation2() {
		System.out.println("operation A 2 mothod");
	}

}

 

package TemplateTest;

public class TemplateB extends TemplateSource {

	@Override
	public void compataOperation1() {
		System.out.println("B1");
	}

	@Override
	public void compataOperation2() {
		System.out.println("B2");
		
	}

}

 

package TemplateTest;

public class Test {

	public static void main(String[] args) {
		TemplateSource a = new TemplateA();
		TemplateSource b = new TemplateB();
		a.template();
		b.template();
	}

}
