将单个字符串保存到数组中，文件文本java中用多个空格隔开

Question

I'm a java beginner and I'm doing a small project about dictionary, now I want to save word and translate mean in file, because my native language often have space like chicken will be con gà so, I must use other way, not by space, but I really don't know how to do that, a word and it translation in one line, separate by "tab", mean multi space like chicken con gà now I want to get 2 words and store it in my array of Words which I created before, so I want to do something like

w1=word1inline;
w2=word2inline;
Word(word1inline,word2inline);(this is a member of array);

please help me, thanks a lot, I just know how to read line from file text, and use split to get word but I am not sure how to read by multi space.

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
public class docfile {
    public static void main(String[] args)
    {
        String readLine;
        ArrayList<String>str=new ArrayList<>(String);
        try {
            File file = new File("text.txt");
            BufferedReader b = new BufferedReader(new FileReader(file));
            while ((readLine = b.readLine()) != null) {
                str.add()=readLine.split("  ");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

If you stick to using tabs as a separator, this should work:

package Application;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

public class Application {
    public static void main(String[] args) {
        String line;
        ArrayList<String> str = new ArrayList<>();
        try {
            File file = new File("text.txt");
            BufferedReader b = new BufferedReader(new FileReader(file));
            while ((line = b.readLine()) != null) {
                for (String s : line.split("\t")) {
                    str.add(s);
                }
            }

            str.forEach(System.out::println);
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

Why not just use a properties file?

dict.properties :

chicken=con gá

Dict.java :

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Properties;

public class Dict {
    public static void main(String[] args) throws IOException {
        Properties dict = new Properties();
        dict.load(Files.newBufferedReader(Paths.get("dict.properties")));
        System.out.println(dict.getProperty("chicken"));
    }
}

Output:

con gá

If your line is like this chicken con gà you can use indexof() method to find the first space in the string.

Then you can substring each word by using substring() method.

    readLine = b.readLine();
    ArrayList<String>str=new ArrayList<>();

    int i = readLine.indexOf(' ');
    String firstWord = readLine.substring(0, i);
    String secondWord = readLine.substring(i+1, readLine.length());

    str.add(firstWord);
    str.add(secondWord);
