Java:线程化时更改标签值 [英] Java: Changing a label value while threading

问题描述

我想创建一个小循环，在按下GUI上的一个按钮后，该值将每秒更改一次；我尝试使用线程，但似乎无法正常工作.现在发生的是，程序在按下按钮后仅暂停了10秒钟.你能帮我吗?

i want to create a little loop where after i press a button on a GUI, a value will change every second; i have tried using a thread but i can't seem to get it working correctly. What now happens is that the program just pauses for 10 seconds after pressing the button. Could you help me?

这是我的代码的样子

private void ButtonActionPerformed(java.awt.event.ActionEvent evt) { 

for (x = 0; x <= 10; x++)
    {

        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
            Thread.currentThread().interrupt(); here.
        }


        nummerlabel.setText(String.valueOf(x));
    }



}
