각 값을 별도의 줄에 추가하는 방법은 무엇입니까?

Question

내 코드는 파일을 읽고 쓰지만 모든 값에 대해 새 줄에 있지 않고 모든 값을 한 줄에 인쇄합니다. 같은 학년으로

// 2 points 
static void Q1(String inputFilename, String outputFilename) { 
    // You are given a csv file (inputFilename) with all the data on a single line. Separate the 
    // values by commas and write each value on a separate line in a new file (outputFilename) 

     String data = ""; 
     try { 
      for(String s :Files.readAllLines(Paths.get(inputFilename))){ 
       data = data + s;

Answer 1

String data = ""; 
try { 
    // input file has all data on one line, for loop isn't necessary here 
    // input file has elements separated by comma characters 
    for(String s : Files.readAllLines(Paths.get(inputFilename))){ 
     data = data + s; 
    } 
    String[] separated = data.split(",");// does not handle embedded commas well 
    data = ""; 
    // output file should have each comma separated value on its own line 
    for (String t : separated) { 
     data = data + t + System.getProperty("line.separator"); 
    } 
    Files.write(Paths.get(outputFilename), data.getBytes()); 
} 

: 그래서, 당신이 코드를 얻을 수 s += "\n"; 추가해야

Answer 2

첫째, 당신은 CSV 파일에서 쉼표를 제거해야합니다.
s = s.replace(",",""); 또한 사용하려면 각 줄에 \n을 추가하여 새 줄에 표시해야합니다.

static void Q1(String inputFilename, String outputFilename) { 
// You are given a csv file (inputFilename) with all the data on a single line. Separate the 
// values by commas and write each value on a separate line in a new file (outputFilename) 

    String data = ""; 
    try { 
     for(String s :Files.readAllLines(Paths.get(inputFilename))){ 
      s.replace(",",""); 
      s += "\n"; 
      data = data + s; 
     } 
     Files.write(Paths.get(outputFilename), data.getBytes()); 
    } catch (IOException e) { 

     e.printStackTrace(); 
    }
