java 按行读取txt文件并存入数组

/*** 从文件中载入测试集** @throws IOException*/public static ArrayList<Tx> loadTestCases(String fileName) throws IOException {System.out.println("================================ 1。 end load testSet ================================");ArrayList<Tx> testSet = new ArrayList<>(); // 测试集BufferedReader br = null;try {br = new BufferedReader(new FileReader(new File(fileName)));String line = null;while ((line = br.readLine()) != null) {line = line.trim();if (!line.isEmpty()) {String[] info = line.split(" ");Tx tx = new Tx(Integer.parseInt(info[1]), Integer.parseInt(info[2]));testSet.add(tx);}}}finally {if (br != null) {br.close();}}// 打印测试for(int i = 0;i < testSet.size(); i ++){System.out.println(testSet.get(i));}System.out.println("================================ 2。 end load testSet ================================");return testSet;}
