讀取文件並將字符串存儲到數組中

Question

我正在嘗試從文件（MoviesList）中獲取一些數據，並將其存儲在變量中，然后進行打印。

該文件包含以下不同的段落：

Fast & Furious7 (2015)
Type: Movie
Director : James Wan 
With : Vin Diesel, Paul Walker, Dwayne Johnson 
Action | Crime | Thriller 137 mins.

這是代碼的摘錄

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.*;


public class FlotTest {
    private static BufferedReader fR;


    public void lireLignes(File f) throws IOException{
         fR= new BufferedReader(new FileReader(f));
        String chaine ="";
         do {
         chaine = fR.readLine();
         if (chaine!= null) {

             String [] tab=chaine.split(","); 
             String MovieName=tab[1]; 

        System.out.println(MovieName);



    }
    }while (chaine != null);
         fR.close();

}
}

這是測試班

package testFlot;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.*;

public class test1 {
    public static void main(String[] args) throws IOException{
        FlotTest t= new FlotTest();
    File f = new File("MoviesList.txt");
       t.lireLignes(f);
    }

Answer 1

我猜您是在將MovieName添加到數組中嗎？ 如果是這樣的話...

聲明一個ArrayList<String>變量（在類級別，假設您想在方法之外訪問它），以及當前正在調用System.out.println ，只需將它們添加到ArrayList變量即可。

Answer 2

如果您已將行讀取並存儲到String chaine中，則可以執行以下操作：

   //String chaine="Fast & Furious7 (2015) Type: Movie Director : James Wan With : Vin Diesel, Paul Walker, Dwayne Johnson Action | Crime | Thriller 137 mins";

    String title = chaine.substring(0, chaine.indexOf("(")-1);

    System.out.println(title);

    String year = chaine.substring(chaine.indexOf("(")+1, chaine.indexOf(")"));

    System.out.println(year);

    String type = chaine.substring(chaine.indexOf(":")+2, chaine.indexOf("Director"));

    System.out.println(type);

    String directors = chaine.substring(chaine.indexOf("Director")+11, chaine.indexOf("With"));

    System.out.println(directors);

    //you'll have to figure out a way to parse the actors in depending on how your file is set up
    //it's interesting you don't have a seperator between Actors and the Genre


    //you could create an array
    String[] movie = new String[7];
    movie[0]= title;
    movie[1]=year;
    movie[2]=type;
    movie[3]=directors;



    //I find arraylists easier to deal with so you could create an arraylist
    ArrayList<String> movieList = new ArrayList<String>();
    movieList.add(title);
    movieList.add(year);
    movieList.add(type);
    movieList.add(type);
    movieList.add(directors);

我停下來是因為我有一些工作要完成，但是您可以輕松地為演員，流派和時間長度添加相似的行，然后將它們添加到數組或arrayList中。
