我是Java新手,这是我聊天机器人代码的一部分。当我从showMenu()
运行createQuestions()
时,它似乎不起作用。createQuestion()
所做的是让用户创建问题并与自己聊天。
问题就在这里
欢迎!
选择您的选项:
1( 添加问题
2(聊天(您需要先添加问题(
3(更多地了解城镇
4( 退出
您: 1
正在创建问题...如果您想停止,请键入"结束" 问题?(它不会在这里暂停,因为我需要阅读用户输入的内容并将其存储为问题(
你:
你想要多少个回复? :
//Start of ShowMenu():

q = txtEnter.getText();
txtChat.append("You: " + q + "n");
if (!q.contains("end")) {
txtChat.append("How many responses do you want? : ");
noOfResponses = Integer.parseInt(txtEnter.getText());
txtEnter.setText("");
String r[] = new String[noOfResponses];
if (noOfResponses > 0) {
for (int i = 0; i < noOfResponses; i++) {
txtChat.append("Response " + (i + 1) + ": ");
r[i] = txtEnter.getText();
txtEnter.setText("");
}
Chat newChat = new Chat(q, r);
addQuestion(newChat);
txtChat.append("n" + Arrays.toString(r));
} else {
txtChat.append("Please enter a number bigger than 0");
}
} else {
showMenu();
}
} while (q.equalsIgnoreCase("end") == false);
}
错误是这些
Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: ""
如果txtEnter.getText()
返回空白,则得到:
java.lang.NumberFormatException: For input string: ""
因为空白不能转换成数字。
因此,您应该检查以确保txtEnter.getText()
不会返回空白。
