How to store the value in the JLabel without it resetting each time the JButton is activated?

I'm creating a program that when you enter a value greater than 18 it adds one to the JLabel however each time I click the button the program resets back to 1 instead of adding an additional one.

For example if I enter another value greater than 18, the JLabel should add an additional one so the total is two...

This is my code:

int age = Integer.parseInt(jTextField1.getText()); // gets the value from the button click

if(age >= 18){ // determines if it is greater then 18
     int totalOne = 0;
     totalOne = totalOne + 1;
     String totalAgeOne = Integer.toString(totalOne);
     jLabel3.setText(totalAgeOne); // sets the jlabel to One
}else{
     int totalTwo = 0;
     totalTwo = totalTwo + 1;
     String totalAgeTwo = Integer.toString(totalTwo);
     jLabel5.setText(totalAgeTwo);    
}

You need to get the current value of the JLabel, and then add one to it.

jLabel3.setText(""+(Integer.parseInt(jLabel3.getText())+1));

Currently, your variable totalOne and totalTwo reset to the value of 0 ever time it runs through the conditional statement because they are local variables.
