範例

在下面的程式碼中展示了如何使用DataOutputStream.DataOutputStream(OutputStream out)建構函式。

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

public class Main {
  public static void main(String[] args) throws IOException {
    String[] s = { "Hello", "from tw511.com!" };
    FileOutputStream fos = new FileOutputStream("c:\\test.txt");
    DataOutputStream dos = new DataOutputStream(fos);

    for (String j : s) {
      dos.writeUTF(j);
    }

    dos.flush();// => W W w . y IIb A I.C o M 

    InputStream is = new FileInputStream("c:\\test.txt");

    DataInputStream dis = new DataInputStream(is);

    while (dis.available() > 0) {
      String k = dis.readUTF();
      System.out.print(k);
    }
  }
}
