如何在ArrayList中保存的字符串之間選擇文本

Question

無法解決這個問題。 我正在使用apache POI從.doc中選擇粗體文本。 我已將此添加到數組列表。 我想從位於arrayList中連續字符串之間的.doc中選擇文本，然后分別存儲每個選定的部分。

換句話說，我有這個：

MyBold title
Bla
bla
fsfs
bn
whtrh

More bold title

gfgdgdfs
dsgfd
gfdg

Another title of some kind

結果arrayList給我這個：

MyBold title
More bold title
Another title of some kind

我想將此作為單獨的字符串對象的第一個對象獲取：

MyBold title
    Bla
    bla
    fsfs
    bn
    whtrh

第二個對象：

More bold title

    gfgdgdfs
    dsgfd
    gfdg

第三個對象：

Another title of some kind

到目前為止，我的代碼：

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;
import org.apache.poi.hwpf.usermodel.Paragraph;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.apache.poi.wp.usermodel.CharacterRun;

public class Impedance {
    String REGEX = "[A-Z]+";
    public Impedance()  {
    }

        // TODO Auto-generated constructor stub
         public static void Update() throws IOException {
    try{
    String fileName = "/Users/IMPEDANCE.doc";
    InputStream fis = new FileInputStream(fileName);  
    POIFSFileSystem fs = new POIFSFileSystem(fis);  
    HWPFDocument doc = new HWPFDocument(fs);  

    Range range = doc.getRange();
    WordExtractor we = new WordExtractor(doc);
    Paragraph r =range.getParagraph(0);
    ArrayList<String> bold1 = new ArrayList<String>();
    for(int i = 0; i<range.numCharacterRuns(); i++)
    {


            CharacterRun cr = range.getCharacterRun(i);
            if(cr.isBold())
            {
            System.out.println(cr.text());
            bold1.add(cr.text());
            }

    }



    for (String bold : bold1) {
    //How to iterate through array list and return the string section between consecutive parts of the arraylist
    }
 }
}

您可以使用Map，其中鍵是標題，值是字符串列表。

Map<String, List<String>> map  = new Hashmap<>();
String currentTitle = null;

for(int i = 0; i<range.numCharacterRuns(); i++){

    CharacterRun cr = range.getCharacterRun(i);

    //if the cr is bold, add it as a title
    if(cr.isBold()){

        currentTitle = cr.text();
        map.put(currentTitle, new ArrayList<String>());

        }else{

            //if the cr is not bold, get the last inserted title and
            //add the cr to its String list

            List<String> list = map.get(currentTitle);

            if(list != null){

                list.add(cr.text());
                map.put(currentTitle, list);
           }

        }
}
