java DataInputStream 和 DataOutputStream将基本类型数据写入文件

package stream;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

public class DataInputStreamTest {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		File file = new File("d:\\test\\tt.txt");
		try {
			FileOutputStream fos = new FileOutputStream(file);
			DataOutputStream dos = new DataOutputStream(fos);
			dos.writeUTF("你好啊，亲");
			dos.writeInt(123);
			FileInputStream fis = new FileInputStream(file);
			DataInputStream dis = new DataInputStream(fis);
			System.out.println(dis.readUTF());
			System.out.println(dis.readInt());
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
	
}

有一个不好的地方就是写入顺序和读出顺序要一样。
