如何在ArrayList中的字符串之间选择文本

Question

无法解决这个问题。我使用apachePOI从.doc中选择粗体文本。我已经将其添加到数组列表中。我想从.doc中选择位于arrayList中连续字符串之间的文本，然后分别存储每个选定的部分。

换句话说，我有这个：

MyBold title
Bla
bla
fsfs
bn
whtrh
More bold title
gfgdgdfs
dsgfd
gfdg
Another title of some kind

得到的arrayList给了我这个：

MyBold title
More bold title
Another title of some kind

我想把它作为单独的字符串对象第一个对象：

MyBold title
    Bla
    bla
    fsfs
    bn
    whtrh

第二个对象：

More bold title
    gfgdgdfs
    dsgfd
    gfdg

第三个对象：

Another title of some kind

到目前为止我的代码：

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，其中键是标题，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);
           }
        }
}
