Question

对于Java来说，我是初学者，而且我的起步很慢。我创建了一个Applet，允许用户在文本字段中输入某个句子，输出告诉用户特定字符数量的单词数量。

我想在完成之前向applet添加更多内容，但我不太清楚如何做这些事情。

首先，我希望applet能够区分单词和标点符号。因此，如果一个单词的末尾有一个感叹号，那么它将包含一个单词的长度。而且，我希望它能告诉用户applet窗口中的平均字长。

其次，我希望信息以条形图形式显示。意思是x轴告诉用户字长，而y轴告诉用户字频。原因很简单，因为我希望程序整洁。

最后，我不太确定是否有可能，但我希望用户可以选择将文件加载到applet中，applet对其中的文本执行单词计数文件。

到目前为止我的代码是：

package org.main;
