我正在尝试从具有以下格式的 txt 文件中读取:
Matthew:1000
Mark:100
Luke:10
John:0
我有一个存储玩家姓名和分数(int)的分数对象。这是 Score 的类:
public class Score {
String playerName;
int playerScore;
public String toString(){
StringBuilder builder = new StringBuilder();
builder.append(playerName + ":" + playerScore);
return builder.toString();
}
public void setName(String name){
this.playerName = name;
}
public void setScore(int score){
this.playerScore = score;
}
}
我想以这样一种方式从文件中读取,我可以得到玩家的名字(马修)和他们的分数(1000,存储为整数),并创建一个新的分数对象。这是我到目前为止尝试过的代码:
public ArrayList getLoadFile(String filename) {
ArrayList<Score> scores = new ArrayList<Score>();
BufferedReader bufferedReader = null;
try{
bufferedReader = new BufferedReader(new FileReader(filename));
String fileLine;
while((fileLine = bufferedReader.readLine()) != null){
Score newScore = new Score();
newScore.playerName = fileLine.split(":", 0)[0];
newScore.playerScore = Integer.parseInt(fileLine.split(":", 0)[1]);
scores.add(newScore);
}
} catch (FileNotFoundException e) {
} catch (IOException e) {
}
return scores;
}
该函数应该加载已保存分数的字符串表示形式并制作分数的 ArrayList,然后将它们返回给测试函数。当我运行它时,它返回: java.lang.ArrayIndexOutOfBoundsException: 1
任何帮助将不胜感激。
