java - 将文件句子拆分为单词

Question

谁能帮帮我？

我正在尝试将其拆分sentences[]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(" ");
        }
    }
}   

我能做些什么？

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(" ");

对此

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

Answer 3

而不是使用 j 变量的 for 循环：

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

分裂看起来像String[]split(String regex)分裂

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

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