Script stukje waar de fout in zit:

private void posnegActionPerformed(java.awt.event.ActionEvent evt) {
        plusminus=(Double.parseDouble(String.valueOf(display.getText()));
        plusminus=plusminus*(-1);
display.setText(String.value.Of(plusminus));
    }

Het werkt nog niet :(.

Gelukt :). Topic kan gesloten worden :$ :slotje:...

Volgens mij was de oplossing wat Killingdevil zei :p.
Nu heb ik een Java rekenmachinetje xD.

Ja, ik had toen ik dat deed een typ foutje, toen dacht ik dat hij het niet deed. Toen keek ik er nog een keer naar en toen zag ik dat typefoutje :P.
