从包含\ n的字符串计算单词

Question

我有下面提到的字符串

String str = "\nArticle\n\nArticle\nArticle";

我想要总数。我怎么能得到这个？ 由于字符串包含\ n所以总是它给出1而不是3

Answer 1

为了帮助您入门，我将向您展示一个简单的示例：

String str = "\nArticle\n\nArticle\nArticle";

// Split the String by \n
String[] words = str.split("\n");

// Keep the count of words
int wordCount = 0;

for(String word : words){
   // Only count non-empty Strings
   if(!word.isEmpty()) {
       wordCount++;
   }
}

// Check, answer is 3
System.out.println(wordCount);
