Question : Java Calculator Problem

Hello Experts,
 I am having a problem developing a calculator that will add all my inputs. for example if i want to add 1+2+3=  then my calculator will only add the 2+3. Other than that the calculator does the correct calculations for 1+2=3 with no problem, its only when i add the third value the output is incorrect. THanks!!!

Answer : Java Calculator Problem

try this:

private void plusActionPerformed(java.awt.event.ActionEvent evt) {

   equalsActionPerformed(null);

   firstDouble=(Double.parseDouble(String.valueOf(display.getText())));
   display.setText("");
   plusClick=1;
   decimalClick=0;
}
