貌似用了 Java8 的语法

javaimport java.util.*;
import java.io.*;

public class Parser {
    private List<State> states;

    public List<State> getStates() {
        return states;
    }

    public void parse(String filename) throws Exception {
        states = new ArrayList<>();
        try (FileInputStream stream = new FileInputStream(filename);
            InputStreamReader iReader = new InputStreamReader(stream, "utf-8");
            BufferedReader reader = new BufferedReader(iReader)) {
            String line;
            while ((line = reader.readLine()) != null) {
                parseLine(line.trim());
            }
        }
    }

    private void parseLine(String line) {
        int index = line.lastIndexOf(' ');
        if (index < 0) {
            return;
        }

        String chinese = line.substring(index + 1);
        String english = line.substring(0, index).trim();

        states.add(new State(english, chinese));
    }

    public static class State {
        public String englishName;
        public String chineseName;

        public State() {}
        public State(String english, String chinese) {
            englishName = english;
            chineseName = chinese;
        }

        @Override
        public String toString() {
            return "[" + englishName + ", " + chineseName + "]";
        }
    }

    public static final void main(String[] args) throws Exception {
        Parser parser = new Parser();
        parser.parse("data.txt");
        for (State s : parser.getStates()) {
            System.out.println(s);
        }
    }
}
