我正在尝试将长值传递给函数。但它说“令牌“长”上的语法错误，删除此令牌“。请解释这是什么以及何时发生这种错误

代码

public static void main(String[] args) {

    Calendar currenttime = Calendar.getInstance();          
    Date date = currenttime.getTime();
    long timeInMillisSinceEpoch = date.getTime(); 
    long ctimeInMinutesSinceEpoch = timeInMillisSinceEpoch / 1000;              
    Calendar subhr = Calendar.getInstance();
    subhr.add(Calendar.HOUR, -1);              
    Date date1 = subhr.getTime();
    long timeInMillisSinceEpoch1 = date1.getTime(); 
    long btimeInMinutesSinceEpoch1 = timeInMillisSinceEpoch1 / 1000;
    //error on this line 
    printCSV(long btimeInMinutesSinceEpoch1,long ctimeInMinutesSinceEpoch); 
}

public static void printCSV(long bdata,long cdata) {
    try {
        URL url = new URL(protocol + "://" + hostname + "/apiv2/csv.xml?username=" + userName + "&password=" + password + "&form_id=" + formId + "&begin_second="+bdata +"&end_second="+cdata);
        HttpURLConnection urlCon = (HttpURLConnection) url.openConnection();
        System.out.println(urlCon);
    }

请帮助我。

更改printCSV(long btimeInMinutesSinceEpoch1,long ctimeInMinutesSinceEpoch); 为

printCSV(btimeInMinutesSinceEpoch1,ctimeInMinutesSinceEpoch);

在将参数传递给函数时，您不需要在函数调用中指定输入参数的数据类型。

就是这一行：

    //error on this line 
    printCSV(btimeInMinutesSinceEpoch1, ctimeInMinutesSinceEpoch);

在调用方法时，您不需要指定输入参数的类型。因此改变这个：

printCSV(long btimeInMinutesSinceEpoch1,long ctimeInMinutesSinceEpoch);

至

printCSV(btimeInMinutesSinceEpoch1,ctimeInMinutesSinceEpoch);

利用：

printCSV(btimeInMinutesSinceEpoch1, ctimeInMinutesSinceEpoch);

没有long。

   long btimeInMinutesSinceEpoch1 = timeInMillisSinceEpoch1 / 1000;
    long ctimeInMinutesSinceEpoch = timeInMillisSinceEpoch / 1000;

在上面的 2 行中，您已经声明btimeInMinutesSinceEpoch1了ctimeInMinutesSinceEpochlong 类型。现在，在这一行 printCSV(long btimeInMinutesSinceEpoch1,long ctimeInMinutesSinceEpoch); 中，您再次声明相同的事情正确答案 printCSV(btimeInMinutesSinceEpoch1,ctimeInMinutesSinceEpoch);
