java - 使用java分割它

Question

我需要分割并串起来

    Sentence:NounPhrase| VerbPhrase
    NounPhrase:Art| Noun
    Sample:the 

这应该写为

Sentence:NounPhrase
Sentence :VerbPhrase
NounPhrase:Art
NounPhrase: Noun
Sample:the

我如何使用java来做到这一点

已编辑

文件表达式.txt

Sentence:NounPhrase VerbPhrase
NounPhrase:Art Noun
VerbPhrase:Verb|Adverb Verb
Art:the|a
Verb:jumps|sings
Noun:dog|cat

我使用过但不工作的程序

   import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.util.*;
public class shift {
    public static String readFileFull(String file)
    {
         String strLine = null;
         StringBuffer sb = new StringBuffer();

        try{

            FileInputStream fstream = new FileInputStream(file);

            DataInputStream in = new DataInputStream(fstream);

            BufferedReader br = new BufferedReader(new InputStreamReader(in));



            while ((strLine = br.readLine()) != null)   {
                sb.append("\n");      
                sb.append(strLine);      
                }



            in.close();
            }catch (Exception e){
              System.err.println("Error: " + e.getMessage());
            }
            String ret=sb.toString();
            return ret;
    }

    public static void main(String args[]) {

        String speech = readFileFull("c://expression.txt");


        StringBuilder sb = new StringBuilder();
        Scanner sc = new Scanner(speech);

        while (sc.hasNextLine()) {
            String[] ps = sc.nextLine().split(":");
            for (String s : (ps[1] + "|").split("\\|"))
                if (!s.equals(""))
                    sb.append(ps[0]+":").append(s).append("\n");
        }
        System.out.println(sb.toString());




    }

}

并尝试告诉我我仍然收到错误

import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.InputStreamReader;

public class FileRead {
    public static void main(String args[]) {
        try {

            FileInputStream fstream = new FileInputStream("c:\\expression.txt");
            DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            String strLine;
            // Read File Line By Line
            while ((strLine = br.readLine()) != null) {

                String a[] = strLine.split(":");
                String b[] = a[1].split("\\|");

                for (String s1 : b) {
                    System.out.println(a[0] + ":" + s1.trim());
                }
            }
            in.close();
        } catch (Exception e) {
            System.err.println("Error: " + e.getMessage());
        }
    }
}

注意:如果您的输入字符串不严格遵守您提到的格式，您将遇到 ArrayIndexOutOfBoundsException...您需要处理这种情况。
