Java将单词读入字符串数组列表

我想通过缓冲读取器将文件game-words.txt读入字符串数组列表。我已经将缓冲读取器设置为从game-words.txt读取，现在我只需要弄清楚如何将其存储在ArrayList中。感谢您的帮助和耐心！ 以下是我到目前为止的情况：

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOExecption;

class Dictionary{
     String [] words; // or you can use an ArrayList
     int numwords;

    // constructor: read words from a file
    public Dictionary(String filename){ }
    BufferedReader br  = null;
    String line;

    try {

        br = new BufferedReader(new FileReader("game-words.txt"));

    while ((line = br.readLine()) != null){
            System.out.println(line);
    }
    } catch (IOExecption e) {

        e.printStackTrace();
    }

}

将字符串读入数组：

自动：

List<String> strings = Files.readAllLines(Path);

可以，您可以使用arrayList存储要添加的单词。 您可以简单地使用以下命令来反序列化文件

ArrayList<String> pList = new ArrayList<String>();

public void deserializeFile(){
    try{
        BufferedReader br = new BufferedReader(new FileReader("file_name.txt"));
        String line = null; 
        while ((line = br.readLine()) != null) {
            // assuming your file has words separated by space
            String ar[] = line.split(" ");
            Collections.addAll(pList, ar);
        }
    }
    catch (Exception ex){
        ex.printStackTrace();
    }
}

这也会有帮助：

class Dictionary{
 ArrayList<String> words = new ArrayList<String>(); // or you can use an ArrayList
 int numwords;String filename;

// constructor: read words from a file
public Dictionary(String filename){ 
     this.filename =filename;
 }
BufferedReader br  = null;
String line;

try {

    br = new BufferedReader(new FileReader("game-words.txt"));

while ((line = br.readLine()) != null){
        words.add(line.trim());
}
} catch (IOExecption e) {

    e.printStackTrace();
}

}

我使用了trim，它将删除单词中的前导空格和尾随空格（如果有）。此外，如果您希望将文件名作为参数传递，请使用Filereader中的filename变量作为参数

您在ArrayList；上查找过Java API吗？返回一个列表你能告诉我如何在我的代码中实现它吗？很抱歉，Java新手！是的，我仍然感到困惑：/@javaPhobicHow文件中存储的单词是什么？每条线上都有吗？它们是用逗号分隔的吗？

ArrayList<String> pList = new ArrayList<String>();

public void deserializeFile(){
    try{
        BufferedReader br = new BufferedReader(new FileReader("file_name.txt"));
        String line = null; 
        while ((line = br.readLine()) != null) {
            // assuming your file has words separated by space
            String ar[] = line.split(" ");
            Collections.addAll(pList, ar);
        }
    }
    catch (Exception ex){
        ex.printStackTrace();
    }
}

class Dictionary{
 ArrayList<String> words = new ArrayList<String>(); // or you can use an ArrayList
 int numwords;String filename;

// constructor: read words from a file
public Dictionary(String filename){ 
     this.filename =filename;
 }
BufferedReader br  = null;
String line;

try {

    br = new BufferedReader(new FileReader("game-words.txt"));

while ((line = br.readLine()) != null){
        words.add(line.trim());
}
} catch (IOExecption e) {

    e.printStackTrace();
}
