Java DataInputStream(InputStream in) 建構函式範例

Java DataInputStream(InputStream in)建構函式範例

DataInputStream(InputStream in)建構函式的語法如下所示。

public DataInputStream(InputStream in)

範例

在下面的程式碼顯示如何使用DataInputStream.DataInputStream(InputStream in)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;
// At:  WWW .yIi  b a I。 CO M
public class Main {
  public static void main(String[] args) throws IOException {
    byte[] b = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    FileOutputStream fos = new FileOutputStream("c:\\test.txt");
    DataOutputStream dos = new DataOutputStream(fos);
    for (byte j : b) {
      dos.writeByte(j);
    }
    dos.flush();

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

    DataInputStream dis = new DataInputStream(is);

    while (dis.available() > 0) {
      int k = dis.read();
      System.out.print(k);
      dis.skipBytes(1);
    }

  }
}
