我想将多个float值存储到数组中，从mysql数据库中检索到，但是它不存储所有值

Question

i want to store multiple float values into array,retrieved from mysql database but it doesn't store all values. it shows only first value iearray[0] to all. while i'm doing System.out.println("bb"+rs2.getFloat(1)); it shows all values correctlly. so kindly help me. i'm pasting my code below.

try{ 
            conn = DB_connection.ConnectDB();

            String s = (String) combocompound.getSelectedItem().toString();
            String s1 = (String) comboelement1.getSelectedItem().toString();
            String s2 = (String) comboelement2.getSelectedItem().toString();

            String sql1 = "SELECT energy FROM compound_data WHERE compound_name=\""+s+"\"";   
            System.out.println("======="+sql1);

            // R (compound)
            String sql2 = "SELECT Log_R FROM compound_data WHERE compound_name=\""+s+"\"";     
            // R1 (element)
            String sql3 = "SELECT Log_R FROM element_type,element_data WHERE element_type.element_id = element_data.element_id AND element_type.element_name=\""+s1+"\""; 
            // R2 (element)
            String sql4 = "SELECT Log_R FROM element_type,element_data WHERE element_type.element_id = element_data.element_id AND element_type.element_name=\""+s2+"\"";                      

            pst1 =conn.prepareStatement(sql1);      
            rs1 = pst1.executeQuery();
            rs1.last();
            int count = rs1.getRow();
            rs1.beforeFirst();
            System.out.println("rowsFirst"+count);

            System.out.println("Upto date: "+rs1.next());
            while (rs1.next()) {
              //System.out.println("aa"+rs1.getFloat(1));
                 for (int i=0; i<count; i++)
                             {
                                 data1[i] = rs1.getFloat(1);

                           }                       
            } 

            pst2 =conn.prepareStatement(sql2);
            rs2 = pst2.executeQuery();
            //int numRow2 = rs2.getRow();
            while (rs2.next()) {
                System.out.println("bb"+rs2.getFloat(1));
                    for (int i=0; i < count; i++)
                             {
                                   data2[i] = rs2.getFloat(1);
                                   //System.out.println("lkjh"+data2[i]);  
                             }      

            }  
            for (int i=0; i < count; i++)
                             {
                                  // data2[i] = rs2.getFloat(1);
                                   System.out.println(i+": "+data1[i]);  
                                   System.out.println(i+": "+data2[i]);  
                             }  
            pst3 =conn.prepareStatement(sql3);
            rs3 = pst3.executeQuery();
            int numRow3 = rs3.getRow();
            while (rs3.next()) {
                System.out.println("aa"+rs3.getFloat(1));
                    for (int i=1; i <= numRow3; i++)
                             {
                                   data3[i] = rs3.getFloat(i);
                                   //System.out.println(data3[i]);
                             }                         
            }  
            pst4 =conn.prepareStatement(sql4);
            rs4 = pst4.executeQuery();
            int numRow4 = rs4.getRow();
            while (rs4.next()) {
                System.out.println("bb"+rs4.getFloat(1));
                    for (int i=1; i <= numRow4; i++) 
                             {
                                   data4[i] = rs4.getFloat(i);
                                  // System.out.println(data4[i]);
                             }                         
            }  
        } catch(SQLException e){
            System.out.println(e);   
          }

and i will shows output like this

 run:

Answer 1

try something like this :

int count = 0

Then in while loop do like this :

while(rs1.next())
{
    data1[count] = rs1.getFloat(1);
    count++;
}
count = 0;

Try doing this for all while loops

Answer 2

Reason is you are going to assign value to same index again and again.

So it print last assigning value as result;

while (rs1.next()) {
    //System.out.println("aa"+rs1.getFloat(1));
    for (int i=0; i<count; i++)
    {
      data1[i] = rs1.getFloat(1); // every time data[0] = rs1.getFloat(1) 

    }                       
} 

try to change your code with following

int i = 0;

while (rs1.next()) {
    //System.out.println("aa"+rs1.getFloat(1));
   data1[i] = rs1.getFloat(1);
   i++;

}
