我正在写一个聊天机器人，但似乎我不能回到起点。 我是一名初学者，所以请帮助我。我已经看到我的代码也有点混乱。我希望你可以阅读他们。感谢您的帮助！我想尽可能简单地回到这段代码的开头。谢谢
public static void main(String[] args) {
Scanner userinput = new Scanner(System.in);
Scanner choice = new Scanner(System.in);
String message;
String GenderInput;
//popup for 1 to chat and 2 to play
boolean gendercheck = false;
我想回到这个代码
的System.out.println（ “请按\” 1 \ “聊天” + “&” + “\” 2 \”打游戏“+”& \“3 \”编辑对话“）;
而不是结束。在我输入结尾后，聊天机器人就会结束而不回到主屏幕。我见过使用方法来做这件事的朋友，但是因为我在这里使用了开关盒，所以我可以轻松地做到这一点吗？
System.out.println("Press \"1\" to chat" + " & " + "\"2\" to play games" + " & \"3\" to edit the conversations");

String returningCode = returnChoiceOfChatbot(startup);
System.out.println(returningCode);

请去看[问]。之后，编辑你的问题，并给它一个正确的标题... – CBroe
这是不是很清楚你问的。你能否详细说明，也许用更简单的例子来演示？您所展示的大部分代码似乎与您所描述的内容完全无关。 – David
如果我理解得很好，并且想要让用户再次选择菜单中的其他选项，只需添加一个while循环（具有测试菜单选项的条件，例如直到用户输入退出选项）包含你的“菜单”和你的开关盒。 – Maaaatt
