标记化字符串中每个标记的字符数,Java
我试图弄清楚是否可以计算每个令牌的字符数并显示这些信息,例如: day是标记化的,我的输出将是:“day有3个字符。”并继续为每个标记这样做 我最后一次打印每个标记中字符的循环从不打印:标记化字符串中每个标记的字符数,Java,java,arraylist,char,tokenize,stringtokenizer,Java,Arraylist,Char,Tokenize,Stringtokenizer,我试图弄清楚是否可以计算每个令牌的字符数并显示这些信息,例如: day是标记化的,我的输出将是:“day有3个字符。”并继续为每个标记这样做 我最后一次打印每个标记中字符的循环从不打印: public static void main(String[] args) { Scanner sc = new Scanner(System.in); ArrayList<String> tokenizedInput = new ArrayList<>();

控制台示例:
请键入至少包含4个单词的句子,最多8个单词:
你好,这是一个测试
多谢各位
您输入:
你好,这是一个测试
句子中的每个单词都是:[你好,这里,这,是,a,测试]首先,我添加了必要的导入,并围绕这个主要方法构建了一个类。这应该可以编译

编译器或IDE会告诉您代码是否可以编译。如果没有,他们会给你错误信息?!但是如果没有一个真实的答案,我们就不能真正说出…@幽灵猫对不起,我不清楚。我没有得到一个错误,但是我没有得到我想要打印到控制台的信息。我将用一个例子来更新我的问题。很抱歉没有包括导入,我没有想到这一点。它们在我的代码中。你的解释很清楚。我真的很感激。我觉得我离这里很近,但我永远都不会到达那里。再次感谢您的帮助。没问题,下次一定要包括它们。你就快到了,我们所有人都会这样。请随时提出您可能有的任何其他问题!我希望将来能像你一样帮助像我这样的人。再次感谢!很高兴听到这个消息。随时
int totalLength = 0;
for (String each : tokenizedInput) {
totalLength += each.length();
System.out.println("Word: " + each + " Length:" + each.length());
