当我按下窗口右上角的x按钮时,我希望我的JavaFX程序清理程序.我怎样才能做到这一点？清理代码是

        JIntellitype.getInstance().cleanUp();

我想隐藏divA并显示divB.如果我单击一个按钮,我想隐藏divB并显示divA.我不想使用JQuery.

当页面加载时,我很难隐藏divA.当我单击按钮时,divB被正确隐藏.

我在文档的开头添加了这个

<script>
    var doNotShow= document.getElementById('divA');
    doNotShow.style.display = 'none';
</script>

问题是,它不起作用.奇怪的是,稍后,我尝试通过按钮点击隐藏divB然后divB隐藏它应该.divA位于文件中的javascript部分之后.

当我尝试将文件上传到ftp服务器时,我收到错误.服务器是远程服务器,但它提供ftp访问.这是我正在使用的代码

        client.connect("ftp.adress.comlu.com");
        client.login("username", "mypass");

        //
        // Create an InputStream of the file to be uploaded
        //
        String filename = "D:/xxx/screen0.png";
        fis = new FileInputStream(filename);

        //
        // Store file to server

我想在java应用程序中下载一个文件,当我尝试它时,它会在我的硬盘驱动器上创建该文件但无法完全下载它.我正在使用ftp4j库来做到这一点.

import it.sauronsoftware.ftp4j.*;
public class Main {
public static void main (String args[]){
    FTPClient client = new FTPClient();
    try{
    client.connect("ftp.myaddress.comlu.com");
    client.login("username", "password");
    System.out.println("Connection created");
    client.download("public_html/ZScreen.png", new java.io.File("d:/xxx/ZScreen.png"));
    System.out.println("Download successful");
    client.disconnect(true);
    }
    catch (Exception FTPException){
    System.out.println("Shit hit the fan");
    }
}
}

我总是创建Connection并且Shit击中粉丝.此外,我的硬盘驱动器上创建了一个文件,但它的大小为0字节.

这是堆栈竞赛
