java - 如何使用java在同一方法中更新具有不同字符串值的变量？

Question

有人可以提供以下建议吗？

private String dataName;
private String sourceType;

public void getConnectionData(){
    DataCollector data = new DataCollector();
    portNumber = data.getConnectionData(sourceType, dataName);
    channel  = data.getConnectionData(sourceType, dataName);
    hostName = data.getConnectionData(sourceType, dataName);    
    queueName = data.getConnectionData(sourceType, dataName);
    queueManager = data.getConnectionData(sourceType, dataName);

}

我有上面的方法，当我尝试使用其他类的方法时，我试图使 dataName 等于上面每个方法的下面的值。

    dataName = "portNumber";    
    dataName = "channel";   
    dataName = "hostName";  
    dataName = "queueName"; 
    dataName = "queueManager";

有人可以告诉我该怎么做吗？

谢谢

为什么不采用通常的方式:

portNumber = data.getConnectionData(sourceType, "portNumber");
channel  = data.getConnectionData(sourceType, "channel");
hostName = data.getConnectionData(sourceType, "hostName");    
queueName = data.getConnectionData(sourceType, "queueName");
queueManager = data.getConnectionData(sourceType, "queueManager");
