按下的按钮的计数 [英] The count number of pressed button

问题描述

我需要，当我按下按钮显示按钮按下了多少次。我使用这种方法，但在控制台上仍显示数字1.

I need that when I press the button to show me how many times was the button pressed. I use this method, but on console still show me the number 1.

这里是代码：

 button_help.setOnMousePressed(new EventHandler<MouseEvent>() {

    @Override
    public void handle(MouseEvent event) {

    int count = 0;
    count ++;

        System.out.println(count);
    }


 });

推荐答案

您的解决方案不会工作，每次单击按钮时变量的值。

Your solution doesn´t work as you are reseting the value of variable every time you click button. You have to define it once and than just increase the valu of it.

解决方案：

int count = 0;

button_help.setOnMousePressed(new EventHandler<MouseEvent>() {

    @Override
    public void handle(MouseEvent event) {
        count++;
        System.out.println(count);
    }

});
