Clear button only makes counter JLabel blank but does not reset it.

I have made this application:

image

For example when I click on the clear button when the counter JLabel (pointsAvailable) is 19 then the counter JLabel goes blank as expected, however when I start adding points again it starts from 19 not 40 as set on the start. I would like to make it to reset back to 40 instead of just making it blank

Code for the clear button

private void JButtonActionPerformed(java.awt.event.ActionEvent evt) {                                        
    speedPoints.setText("");
    attackPoints.setText("");
    defencePoints.setText("");
    powerPoints.setText("");
    agilityPoints.setText("");
    focusPoints.setText("");
    availablePoints.setText("");
}

Code for Jlabel counter 

    public class addingPointsUI extends javax.swing.JFrame {
int pointsAvailable=40;
        int speed=0;
        int power=0;
        int focus=0;
        int agility=0;
        int defence=0;
        int attack=0;

Code for buttons +/-: to allow me to add or decrease value "example power - button"

private void powerMinusActionPerformed(java.awt.event.ActionEvent evt) {                                           
    if (power > 0 ){
        if (pointsAvailable <= 0) {
    JOptionPane.showMessageDialog(null, "You are out of available points");
    return;
        }
        power = power - 1;

        pointsAvailable = pointsAvailable +1;

        availablePoints.setText(String.valueOf(pointsAvailable));

        powerPoints.setText(String.valueOf(power));

    }else {

            JOptionPane.showMessageDialog(null,"You cannot take anymore points from Power");
    }
}

Thank your for your kind replies.

Use a JSpinner with SpinnerNumberModel. Change the value of the model. The component will update and further changes will act on the current value of the model.

Found my own solution on google:

private void ClearActionPerformed(java.awt.event.ActionEvent evt) {     
speedPoints.setText(String.valueOf(0));
powerPoints.setText(String.valueOf(0));
agilityPoints.setText(String.valueOf(0));
defencePoints.setText(String.valueOf(0));
focusPoints.setText(String.valueOf(0));
attackPoints.setText(String.valueOf(0));
availablePoints.setText(String.valueOf(40));
 }

Works perfectly

I can quickly think of two solutions: 1. In the event handler of your clear button include the following: 

private void JButtonActionPerformed(ActionEvent evt){
    ...
    pointsAvailable=40;
    speed=0;
    power=0;
    focus=0;
    agility=0;
    defence=0;
    attack=0;
}

This will reset all of your stats. 2. Or you can add an if statement to the listeners of every button that adds or subtracts a stat that will check if the specific statistic is empty. For example, for the speed buttons the code would look like so:

if (speedPoints.getText() == ""){
    pointsAvailable += speed;
    speed = 0;
}
