hello please, may some one explain this issue : i cant find the code which instantiate the evt object in the following which is generated by netbeans : may some one explain this issue in netbeans (java) : i can't find the code which **instantiate** the **evt** object of KeyEvent Class in the following java code which is generated by netbeans :

    textPrice.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyTyped(java.awt.event.KeyEvent evt) {
                textPriceKeyTyped(evt);
            }
        });

where i can find the source code that instantiate the **evt** object of KeyEvent class?
 
can we call **evt** methods without instantiating it like this code below?

  

     private void textPriceKeyTyped(java.awt.event.KeyEvent evt) {                                   
        // TODO add your handling code here:
        char c = evt.getKeyChar();
        if(!(Character.isDigit(c) )||(c==KeyEvent.VK_BACKSPACE) || (c==KeyEvent.VK_DELETE)){
        getToolkit().beep();
        evt.consume();
            
        }
    }
