[FIXED] input in text field only number in java application

Issue

DishFormPanelistIdLbl.setText("Panelist ID:");

        DishFormPanelistIdTxt.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                DishFormPanelistIdTxtActionPerformed(evt);
            }
        });

I have here a text label and text field for ID i want to input only numbers in text how is it possible?been trying the sample program un net beans but they dont have such a solution for this problem any help is appreciated

"Update"

What i want here is when i type letter nothing will show but when number then it will show

Solution

What i did is in the design mode i right click the text field > Events > Key > KeyTyped

then in the code i hade something like this

private void DishFormPanelistIdTxtKeyTyped(java.awt.event.KeyEvent evt) {                                               
        // TODO add your handling code here:
        char enter = evt.getKeyChar();
        if(!(Character.isDigit(enter))){
            evt.consume();
        }
    } 

i didnt get the solution here in stack but i will link it this is the link
