formatdatato.java

这一些程序都是实验之用

import java.io.*;
public class FormatDataTo{
	public static void main(String args[])throws IOException {
		FileOutputStream out1=new FileOutputStream("D:\\javaprogram\\test.txt");
		BufferedOutputStream out2=new BufferedOutputStream(out1);
		DataOutputStream out=new DataOutputStream(out2);
		out.writeByte(-12);
		out.writeLong(12);
		out.writeChar('1');
		out.writeUTF("好");
		out.close();
	
		InputStream in1=new FileInputStream("D:\\javaprogram\\test.txt");
		BufferedInputStream in2=new BufferedInputStream(in1);
		DataInputStream in=new DataInputStream(in2);
		System.out.print(in.readByte()+" ");
		System.out.print(in.readLong()+" ");
		System.out.print(in.readChar()+" ");
		System.out.print(in.readUTF()+" ");
	}
}
