Tengo un método a través del cual puedo filtrar filas por múltiplo de diez, es decir, puedo filtrar las filas más cercanas a múltiplos de decenas, como 10,20,30, etc. en orden ascendente. Ahora quiero hacer el mismo proceso en orden decreciente.

Por favor, consulte el siguiente enlace¿Filtrar la matriz en una fila por múltiplo de diez, según la diferencia?

En el enlace mencionado anteriormente, el mismo proceso se realiza en orden ascendente, quiero hacer esto en orden decreciente y almacenar los valores en el mapa, pero no puedo hacerlo.

Estoy usando el siguiente código para recuperar filas donde beam_current es múltiplo de diez en orden creciente.

public static  LinkedHashMap<Double, String> ClosestToMultiplesOfTen_User() throws SQLException {

    int row_id ;
    int bIdx = 0;
    double[] vals = new double[34];
   // double[] bucket =new double[bucketCount];
    int rowIndex = 0 ;
    int i=0;

    try
            { 
              con = getConnection();
              stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
           //   String sql="select logtime,beam_current from INDUS2_BDS.dbo.DCCT where logtime between '"+name+" 00:00:00' and '"+name+" 23:59:59'"+
            //  "and (beam_current like '%9.96' or beam_current like '%9.97' or beam_current like '%9.98' or  beam_current like '%9.99'  or beam_current like '%0' or beam_current like '%_0.01' or beam_current like '%_0.02' or beam_current like '%_0.03' or beam_current like '%_0.04' or beam_current like '%_0.05' or beam_current like '%_0.06') and beam_energy between '550' and '552'";

              String sql="select logtime,beam_current from INDUS2_BDS.dbo.DCCT where logtime between '2014-10-10 08:50:00' and '2014-10-10 12:50:00'"+
                      "and (beam_current like '%9.96' or beam_current like '%9.97' or beam_current like '%9.98' or  beam_current like '%9.99'  or beam_current like '%0' or beam_current like '%_0.01' or beam_current like '%_0.02' or beam_current like '%_0.03' or beam_current like '%_0.04' or beam_current like '%_0.05' or beam_current like '%_0.06')";

              System.out.println("Value of sql of ClosestToMultiplesOfTen_User is"+sql);
              stmt.executeQuery(sql);
              rs = stmt.getResultSet();
       while(rs.next()) 
        {
           for(int j=0; j<1; j++)
             {
               vals[i]  = rs.getDouble(2);
             }
            i++;
         }
        }
     catch( Exception e )
        {
            System.out.println("\nException "+e);
        }
    //  get the max value, and its multiple of ten to get the number of buckets
    double max = java.lang.Double.MIN_VALUE;
    for (double v : vals) max = Math.max(max, v);
    int bucketCount = 1 + (int)(max/10);
    double[] bucket =new double[bucketCount];

    //  initialise the buckets array to store the closest values
   double[][] buckets = new double[bucketCount][3];
 for (int i1 = 0; i1 < bucketCount; i1++){
        // store the current smallest delta in the first element
        buckets[i1][0] = java.lang.Double.MAX_VALUE;

        double mult = getMultipleOfTen(v);

        double delta = Math.abs(mult - v);
        //  get the bucket index based on the value of `mult`

      // System.out.println("value of bidx for bucket index is"+bIdx);
        //    test the last known "smallest delta" for this bucket
        if (buckets[bIdx][0] > delta)
        {
         //  this is closer than the last known "smallest delta"
          buckets[bIdx][0] = delta;
          buckets[bIdx][1] = row_id;
          buckets[bIdx][2] = v;

        }
     }  
   //   print out the result
 for (int i1 =1; i1 <buckets.length; i1++)
   {
         bucket = buckets[i1];
         rowIndex = (int) bucket[1];
         int row_no=rowIndex+1;
         double rowValue = bucket[2];
         System.out.println("row index "+row_no+ "value is "+rowValue);
         DecimalFormat twoDForm = new DecimalFormat("#.##"); 

         rs.absolute(rowIndex);
         user_current_map.put(java.lang.Double.valueOf(twoDForm.format(rs.getDouble(2))),(rs.getString(1)));
        // map1.put(rs.getString(2),(rs.getString(1)));
         //l.add(map1);
     }
System.out.println("user_current_map "+user_current_map);

return user_current_map;
}

public static  double getMultipleOfTen(double v)
{
     System.out.println(10d * Math.round(v / 10d));
    return 10d * Math.round(v / 10d);
}

Ahora solo quiero invertir el orden, es decir, ahora quiero disminuir el orden de beam_current, es decir, 210,22,190, etc.
