e567. getting all created frames in an application.txt

这里面包含了一百多个JAVA源文件

// Retrieve all active frames
    Frame[] frames = Frame.getFrames();
    
    for (int i=0; i<frames.length; i++) {
        // Get frame's title
        String title = frames[i].getTitle();
    
        // Determine if the frame is visible
        boolean isVisible = frames[i].isVisible();
    }
