这段代码似乎有问题，但我不知道为什么:
System.out.println(line);
// prints: Some Name;1|IN03PLF;IN02SDI;IN03MAP;IN02SDA;IN01ARC
String args[] = line.split("|");
String candidatArgs[] = args[0].split(";");
String inscrieriString[] = args[1].split(";");
System.out.println(args[0]);
System.out.println(args[1]);
System.out.println(candidatArgs);
System.out.println("[0]:" + candidatArgs[0]);
System.out.println("[1]:" + candidatArgs[1]);
// prints: S
// [Ljava.lang.String;@4f77e2b6
// [0]:
我不知道为什么会这样。按照我的逻辑:
String args[] = line.split("|");
[0]: Some Name;1
[1]: IN02SDI;IN03MAP;IN02SDA;IN01ARC
代替:
[0]: S
如果你想要更多的代码:即使它做的不多(尽可能多地删除了不必要的代码)，它也应该可以编译
主要:
有一个文件: Candidati.txt
包含: Some Name;1|IN03PLF;IN02SDI;IN03MAP;IN02SDA;IN01ARC
import java.util.ArrayList;
Repository repository = new Repository ("Candidati.txt"); // file name
ArrayList<Candidat> candidati = repository.getCandidati();
System.out.println(candidati);
存储库
import java.util.ArrayList;
public class Repository {
private String fisierCuCandidati;
private ArrayList<Candidat> listaCandidati;
public Repository (String fisierCuCandidati) {
this.fisierCuCandidati = fisierCuCandidati; // file name
this.listaCandidati = new ArrayList<Candidat>();
this.incarcaCandidati();
}
public void incarcaCandidati() {
FileReader in = null;
BufferedReader input = null;
//try {
in = new FileReader (this.fisierCuCandidati);
input = new BufferedReader (in);
String line;
while ((line = input.readLine()) != null) {
System.out.println(line);
String args[] = line.split("|");
String candidatArgs[] = args[0].split(";");
String inscrieriString[] = args[1].split(";");
System.out.println(args[0]);
System.out.println(args[1]);
System.out.println(candidatArgs);
System.out.println("[0]:" + candidatArgs[0]);
System.out.println("[1]:" + candidatArgs[1]);
}
}
