将文件句子分成单词

Question

有人可以帮我吗？

我正在尝试将sentences[]拆分为words[]。但它显示Syntax error on token "j", delete this token ...

我的代码是：

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(" ");
        }
    }
}   

我该怎么办？

Answer 1

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

这不是有效的String或String array声明。

Answer 2

String.split()返回一个数组。所以你必须改变

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

到这个

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

Answer 3

而不是使用j变量的循环使用：

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

对于多维数组：

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

拆分看起来像String[]split(String regex) split

所以改变你的String word[j] = sentences[i].split(" "); 到

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