Java – use jtextfield – cannot convert value to int

I want to start from JCombo@R_333_2419 @Get the selected value in, search for it in the database, and update the quantity in the database with the value in jtextfield This is the code:

Object selected = jCombo@R_333_2419@1.getSelectedItem();
    String album = (String)selected;
    int qty=Integer.parseInt(jTextField7.getText());
    String query2="update  productlist set QtyAvail=? " +
                "where Album=?";
        try
        {
            PreparedStatement ps2=con.prepareStatement(query2);
            ps2.setInt(1,qty);
            ps2.setString(2,album);
            int res1=ps2.executeUpdate();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

I received this error:

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException:
  For input string: " 1"
    at java.lang.NumberFormatException.forInputString(UnkNown Source)
    at java.lang.Integer.parseInt(UnkNown Source)

    at AddProductPanel.access$4(AddProductPanel.java:335)
    at AddProductPanel$5.actionPerformed(AddProductPanel.java:133)

I enter the value "1" in the text field

Solution

If there is a space in the string entered into parseint(), use trim()
