How to control a loop using a button?

I am a beginner in java, I want to know is there any possible way to control a loop by clicking a button? I am creating a GUI, and it's supposed to run 10 times in the loop. Is there a way that I could have a button on the screen so that when the user presses, then it goes to the next iteration? Because currently everything just runs and executes once.

You can use javaFX it's gonna replace javaswing very soon anyways plus it's cooler.

import javafx.scene.control.button

Button button = new Button("control");
       int i = 0;
        button.setOnAction(new EventHandler<ActionEvent>() {
        @Override public void handle(ActionEvent e) {
        i++;
        label.setText("i increased");
     }
});

In your java class, you should define an attribute and each time you click on the button you add 1 to this attribute and do the action.

define an attribute in your class;

public int i = 0;

and create a button to be clicked on: 

private void clickMeButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                 
    // code your action here:
    this.i++;
 }

You could have the loop wait for the button click, and then once it loops 10 times break the loop.
