Java中的讀取與寫入檔案可以透過FileReader和FileWriter完成
讀取檔案(使用BufferedReader方便讀取整行)
1 | import java.io.FileReader; |
2 | import java.io.BufferedReader; |
3 | import java.io.IOException; |
5 | public static void main(String [] argv) throws IOException { |
6 | FileReader fr = new FileReader("FileName"); |
7 | BufferedReader br = new BufferedReader(fr); |
9 | System.out.println(br.readLine()); |
寫入檔案
1 | import java.io.FileWriter; |
2 | import java.io.IOException; |
4 | public static void main(String [] argv) throws IOException { |
5 | FileWriter fw = new FileWriter("test.txt"); |
