我知道这个问题在网络和 stackoverflow 上被广泛报道，但我可以通过一些额外的帮助来解决这个问题。我收到与加载 Newtonsoft 相关的运行时错误，请参见下文；
[11/07/2020 18:37:17] A ScriptHost error has occurred

任何帮助表示赞赏!
我是Java的新手,而且我遇到了一堵砖墙.我想从另一个类访问GUI组件(在一个类中创建).我正在从一个类创建一个新的GUI类,就像这样;
GUI gui = new GUI();
我可以访问该类中的组件,但是当我去另一个班级时我不能.我真的只需要访问JTextAreas更新他们的内容.有人能指出我正确的方向,任何帮助都非常感谢.
GUI 类:
public class GUI {
JFrame frame = new JFrame("Server");
...
JTextArea textAreaClients = new JTextArea(20, 1);
JTextArea textAreaEvents = new JTextArea(8, 1);
public GUI()
{
frame.setLayout(new FlowLayout(FlowLayout.LEADING, 5, 3));
...
frame.setVisible(true);
}
}
正如标题所说,得到错误"outputsteam是抽象的".我是Java的新手,所以不太确定如何解决它.我的程序正在尝试使用此代码将套接字上的连接的arraylist发送到客户端;
public void sendList(Socket clientSocket, ArrayList connections) throws IOException
{
OutputStream outputStream = new OutputStream(clientSocket.getOutputStream(), true);
ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);
objectOutputStream.writeObject(connections);
System.out.println("List sent");
}
提前致谢!
