貌似用了 Java8 的语法

javaimport java.util.*; import java.io.*; public class Parser { private List states; public List 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); } } }
