Java 设置类的枚举值

我有一个类，即下面提供的

OrderProviderData

public class OrderProviderData {

    public enum TradingInterface {CX_CLIENT, CX_SERVER, CX_ADMIN, CX_ENGINE}

    private boolean easyTrade = false;

    private OrderPreSelect order;
    private String[] event;

    public OrderPreSelect getOrder() {
        return order;
    }

    public void setOrder(OrderPreSelect order) {
        this.order = order;
    }

    public String[] getEvent() {
        return event;
    }

    public void setEvent(String[] event) {
        this.event = event;
    }
}

我想为中的

OrderProviderData

实例设置值

receiveEvent

基于某些条件的方法

public final class OrderProvider extends BlockingDatabaseOrderWorker {

    // some code to initiate here 

    @Override
    public final Object receiveEvent() throws Exception {

        OrderProviderData data = null;

        // get + store the TradingInterface value "tradingIf" here   
        // set the value inside the "switch" condition      

        switch(tradingIf){

            data = new OrderProviderData();

            // set the TradingInterface here
            case value1:
               //set 
               break;  //optional  

            case value2:
              //set 
              break;  //optional  

            default:
               // some code 
         }
    }

    // varify whether the easyTrade is true 
    // set the boolean 
}

我如何正确地书写它？我也愿意接受更好的建议

将enum as字段添加到类中。您只定义枚举本身。（还需要getter和setter）

公共类OrderProviderData{

public enum TradingInterface {CX_CLIENT, CX_SERVER, CX_ADMIN, CX_ENGINE}

private boolean easyTrade = false;

private TradingInterface tradingInterface;

private OrderPreSelect order;
private String[] event;

public OrderPreSelect getOrder() {
    return order;
}

public void setOrder(OrderPreSelect order) {
    this.order = order;
}

public String[] getEvent() {
    return event;
}

public void setEvent(String[] event) {
    this.event = event;
}

public TradingInterface getTradingInterface() {
    return tradingInterface;
}

public void setTradingInterface(TradingInterface tradingInterface) {
    this.tradingInterface = tradingInterface;
}

}

然后，您可以

切换

案例（即枚举的值）。您不能在

开关

和第一个

案例

@Override
public final Object receiveEvent() throws Exception {
    Server f = new Server();

    switch (f.getInf()) {
    case CX_CLIENT:
        // set
        break; // optional

    case CX_SERVER:
        // set
        break; // optional

    default:
        // some code
    }

}

首先，您必须将

tradinterface

字段添加到

OrderProviderData

类中。第二，在切换到

之后，您只能列出案例，而不能列出其他任何内容。看起来您是在要求我们完成您的工作，而不是针对某个特定问题进行阻止。但是，为了帮助您，您的
receiveEvent
方法不应该将类似事件的内容作为参数吗？您可以在其中传递

？
