The two threads are in another class file. From the class that contains the threads, how can I access the JFrame instance in order to change value that are displayed?

推荐答案

要访问另一个类中的私有实例，我认为您应该使用agetter. 示例:

To have access to a private instance within another class, I think you should use agetter. Example:

//JFrame declaration
private JFrame frame;
//Getter
public JFrame getFrame() {
    return frame;
}
