將文件句子拆分為單詞

Question

有人可以幫我嗎？

我正在嘗試將sentences[]分解為words[] 。 但是它Syntax error on token "j", delete this token顯示Syntax error on token "j", delete this token ...

我的代碼是：

try
{
    int j;
    String paragraph = sample.readFileString(f);
    String[] sentences = paragraph.split("[\\.\\!\\?]");
    for (int i=0;i<sentences.length;i++)
    {  
        System.out.println(i);
        System.out.println(sentences[i]);  
        for( j=0;j<=i;j++)
        {
            String  word[j]=sentences[i].split(" ");
        }
    }
}   

我能做什么？

Answer 1

String  word[j]=sentences[i].split(" ");
          ^^^^^^^^

這不是有效的String或String array聲明。

Answer 2

String.split()返回一個數組。 所以你必須改變

String word[j] = sentences[i].split(" ");

對此

String[] word = sentences[i].split(" ");

Answer 3

代替使用j變量的for循環，請使用：

String[] words = sentences[i].split(" ");

對於多維數組：

String paragraph = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras non varius nisi. In at erat est, sit amet consectetur est. ";
String[] sentences = paragraph.split("[\\.\\!\\?]");

String[][] words = new String[sentences.length][];

for (int i=0;i<sentences.length;i++) {  
   words[i] = sentences[i].trim().split(" ");
}

System.out.println(words[0][1]); //[sentence][word] - it would be second word of first sentence

Answer 4

split看起來像String[]split(String regex) split

因此，請更改您的String word[j] = sentences[i].split(" "); 至

String  word[] = sentences[i].split(" ");
