关于Java 设计模式 策略模式 Strategy

1、Context.java

package com.ssm.cts.pattern.strategy;

public class Context {
  private Strategy straegy;

  public Context(Strategy _strategy) {
    this.straegy = _strategy;
  }

  public void operate() {
    this.straegy.operate();
  }
}

2、Strategy.java

package com.ssm.cts.pattern.strategy;

public interface Strategy {
  public void operate();
}

3、TCStrategy.java

package com.ssm.cts.pattern.strategy;

public class TCStrategy implements Strategy {

  @Override
  public void operate() {
    System.out.println("推送优惠券，拉动人气");
  }

}

4、SaleStrategy.java

package com.ssm.cts.pattern.strategy;

public class SaleStrategy implements Strategy {

  @Override
  public void operate() {
    System.out.println("上线早餐、夜宵，提升营业额");

5、Demo.java

package com.ssm.cts.pattern.strategy;

public class Demo {

  // 测试
  public static void main(String[] args) {
    Context context;
    // TC增长策略
    System.out.println("TC增长策略");
    context = new Context(new TCStrategy());
    context.operate();
    
    // 营业额增长策略

    context = new Context(new SaleStrategy());
    context.operate();
  }
