如何从.csv文件创建另一个类的对象？

Question

我正在处理一项任务，要求我使用流API从.csv文件中读取，遍历每一行并使用这些行构建一个对象。对象类称为Planet，它是：

public Planet(String name, long inhabitants, boolean stargateAvailable, boolean dhdAvailable, List<String> teamsVisited) {

}

public String getName() {
    return name;
}

public long getInhabitants() {
    return inhabitants;
}

public boolean isStargateAvailable() {
    return stargateAvailable;
}

public boolean isDhdAvailable() {
    return dhdAvailable;
}

public List<String> getTeamsVisited() {
    return teamsVisited;
}

@Override
public String toString() {
    return name;
}

}

因此，使用流API来遍历.cvs文件的每一行，我需要创建类Planet的对象。

我没有取得任何进展，因为我真的不确定如何使用流API

public class Space {

     public List<Planet> csvDataToPlanets(String filePath) {
         return null;
     }

Answer 1

尝试下面的代码段。

 File inputF = new File(inputFilePath);
  InputStream inputFS = new FileInputStream(inputF);
  BufferedReader br = new BufferedReader(new InputStreamReader(inputFS));
  // skip the header of the csv
  inputList = br.lines().skip(1).map(mapToItem).collect(Collectors.toList());
  br.close();

Answer 2

public static void main(String args[]) {

    String fileName = "<Your File Path"";

    try (Stream<String> stream = Files.lines(Paths.get(fileName))) {

        stream.forEach(<Method to split the string based with ',' as delimiter and call Constructor using Reflection API>);

    } catch (IOException e) {
        e.printStackTrace();
    }

}
