将文件句子拆分为单词

Question

can anyone help me please?

I'm trying to split the sentences[] into words[] . But it shows Syntax error on token "j", delete this token ...

My code is:

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(" ");
        }
    }
}   

What can I do?

Answer 1

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

this is not a valid String or String array declaration.

Answer 2

String.split() returns an array. So you have to change

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

to this

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

Answer 3

Instead of for loop with j variable use:

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

For multidimensional array:

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 looks like String[]split(String regex) split

so change your String word[j] = sentences[i].split(" "); to

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