java - How can I perform the action of a button without clicking the button? -

-

this question has answer here:

i want perform action done when button pressed without clicking button. asking simply, can perform 2 action listeners when single button clicked?

you can solve problem calling method when button clicked. see example: although button isn't pressed, can perform same action.

public class buttontest extends javax.swing.jframe {     private javax.swing.jbutton jbutton1;     private javax.swing.jlabel jlabel1;          /**      * creates new form buttontest      */     public buttontest() {         initcomponents();          changelabeltext();     }      private void changelabeltext() {         if(jlabel1.gettext().equals("1"))             jlabel1.settext("2");         else             jlabel1.settext("1");     }      private void initcomponents() {          jlabel1 = new javax.swing.jlabel();         jbutton1 = new javax.swing.jbutton();          setdefaultcloseoperation(javax.swing.windowconstants.exit_on_close);          jlabel1.settext("1");         jlabel1.setverticalalignment(javax.swing.swingconstants.top);         getcontentpane().add(jlabel1, java.awt.borderlayout.center);          jbutton1.settext("click");         jbutton1.addactionlistener(new java.awt.event.actionlistener() {             public void actionperformed(java.awt.event.actionevent evt) {                 changelabeltext();             }         });         getcontentpane().add(jbutton1, java.awt.borderlayout.page_end);          pack();     }                            /**      * @param args command line arguments      */     public static void main(string args[]) {         java.awt.eventqueue.invokelater(new runnable() {             public void run() {                 new buttontest().setvisible(true);             }         });     }                            }
