策略架构：

public class Context {
private Strategy strategy;
/**
* 策略方法
*/
public void contextStrategy () {
strategy.strategyInterface();
}
}

//策略接口

public interface Strategy {

public void strategyInterface();

}

//策略实现

public class ConcreteStrategyA implements Strategy {
/**
* 策略方法
*/
public void strategyInterface() {
System.out.println("ConcreteStrategyA ...");
}

}
