请推荐一种智能,优雅的方式来编写这些重复的"if"语句

// 定义策略接口
interface Strategy {
    void execute();
}

// 具体策略类1
class ConcreteStrategy1 implements Strategy {
    public void execute() {
        // 具体条件1的逻辑实现
    }
}

// 具体策略类2
class ConcreteStrategy2 implements Strategy {
    public void execute() {
        // 具体条件2的逻辑实现
    }
}

// 策略上下文类
class Context {
    private Strategy strategy;

    public void setStrategy(Strategy strategy) {
        this.strategy = strategy;
    }

    public void executeStrategy() {
        strategy.execute();
    }
}

// 使用策略模式
public class Main {
    public static void main(String[] args) {
        Context context = new Context();

        // 根据具体条件选择合适的策略
        if (condition1) {
            context.setStrategy(new ConcreteStrategy1());
        } else if (condition2) {
            context.setStrategy(new ConcreteStrategy2());
        }

        // 执行策略
        context.executeStrategy();
    }
}
