我用 Java 編寫了一個返回 2 個值的方法。第一個結(jié)果計數(shù)是 int 類型，如果方法是成功 true/false 布爾類型，則為第二個。如何返回兩個值？因此，如果該方法成功，則僅繼續(xù)。示例代碼：public static void main(String args[]){    int count = 0;    boolean status = false;    //count = retrieveData(); Current code working but captures only 1 values at a time i.e. Count not the status    /* Expected Code    if (status == true)  // where status and count is returned from retrieveData method    {        count = retrieveData();        System.out.println("Status is true so can proceed");    }    else        System.out.println("Status is not true so don't proceed");    */}public static int retrieveData() throws  Exception     {        boolean success = false;        String query = "SELECT Count(1) FROM Account";        int totalCount=0;        ResultSet rsRetrieve = null;            Statement stmt = null;            stmt = conn.createStatement();            rsRetrieve = stmt.executeQuery(query);            while (rsRetrieve.next())            {                totalCount= rsRetrieve.getInt(1);                System.out.println("totalCount : "+totalCount);            }        success = true;        return totalCount; // current working code but returns only 1 value i.e. Count not status        /*   Expected        return success + totalCount        */    }
