                {
                    jTextField(String.valueOf(i)).setText("")

                }

but it is error in this way , how to do it ?

Answer 1

So you need something like this

ArrayList<JTextField> fields = new ArrayList<JTextField>(); //This needs to be populated with your JTextFields
for(int i = 0; i < fields.size(); i++)
    if(fields.get(i) != null)
        fields.get(i).setText("");
