My code shows java.lang.NullPointerException while I tried to name JLabel from the the data of database. How can I fix it?

Question

                     found1[found].setText(s1);
                     found2[found].setText(s2);
                     found3[found].setText(s3);
                     found4[found].setText(s4);
                     found5[found].setText(s5);
                     found6[found].setText(s6);
                     found7[found].setText(s7);
                     found8[found].setText(s8);

Here found1[10], ....... , found8[10] are the name of JLabel and I want to name them as per the String name s1, s2, s3..... ,s8 whose names are assigned in the way as shown below:

                     String s1=String.valueOf(rs.getInt(1));
                     String s2=rs.getString(2);
                     String s3=String.valueOf(rs.getInt(3));
                     String s4=rs.getString(4);
                     String s5=rs.getString(5);
                     String s6=rs.getString(6);
                     String s7=rs.getString(7);
                     String s8=String.valueOf(rs.getInt(8));

Here rs is an object of ResultSet class and I am accessing data from table of database. All other codes are correct but I get runtime error every time when I reach at this code.
