java - 如果第一个字母是大写则删除单词

Question

我试图忽略首字母大写的单词并将其他单词添加到列表中。但不幸的是，它确实没有删除任何内容，所有单词都被添加到 List 中。这里出了什么问题？

import java.io.*;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.List;

public class Main {

    private char[] capLetters = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
    private StringBuffer strBuffer = new StringBuffer("");
    private List <String>  wordList= new ArrayList();

    public Main()
    {
        File f =new File("C:/xxx/COMMON.txt");
        try {
            BufferedReader br = new BufferedReader(new FileReader(f));
            String str = "";
            int number =0;

            while((str=br.readLine())!=null)
            {

                //Remove the words with first letter capital
                for(int i=0;i<capLetters.length;i++)
                {
                    if(str.charAt(0)==capLetters[i])
                    {

                    }
                    else
                    {
                        wordList.add(str);
                        break;
                    }
                }             


                number++;

            }

            System.out.println(number);

            for(int i=0;i<wordList.size();i++)
            {
                System.out.println(wordList.get(i));
            }

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    public static void main(String[] args) {
        // TODO code application logic here
        System.out.println("Netbeans Version");  
        new Main();
    }


}

你可以这样做

 while((str=br.readLine())!=null)
 {
     if(!Character.isUpperCase(str.charAt(0)))
     {
           wordList.add(str);
     }
     number++;
 }
