设计模式01-模板设计模式

父类编写算法结构码，子类实现逻辑细节；

public class TemplateMethod {

    public final void print(String message) {
        System.out.println("##########");
        wrapPrint(message);
        System.out.println("##########");
    }

    protected void wrapPrint(String message) {
    }

    public static void main(String[] args) {
        TemplateMethod tm1 = new TemplateMethod(){
            @Override
            protected void wrapPrint(String message) {
                System.out.println("#"+message+"#");
            }
        };
        TemplateMethod tm2 = new TemplateMethod(){
            @Override
            protected void wrapPrint(String message) {
                System.out.println("*"+message+"*");
            }
        };
        tm1.print("Hello Thread");
        tm2.print("Hello Thread");
    }

}
