printstreamtester.java

接着上次传入一些Java学习中的实验

import java.io.*;
public class PrintStreamTester{
	private static void readBuff(byte[]buff)throws IOException{
		ByteArrayInputStream in=new ByteArrayInputStream(buff);
		int data;
		while((data=in.read())!=-1)
		 System.out.print(data+" ");
		 System.out.println();
		 in.close();
		 
	}
	public static void main(String args[])throws IOException{
		ByteArrayOutputStream out=new ByteArrayOutputStream();
		PrintStream ps=new PrintStream(out,true);
		ps.print("好");
		ps.close();
		byte[]buff=out.toByteArray();
		System.out.println("采用本地默认操作系统字符编码");
		readBuff(buff);
		
		out=new ByteArrayOutputStream();
		DataOutputStream ds=new DataOutputStream(out);
		ds.writeUTF("好");
		ds.close();
		
		buff=out.toByteArray();
		System.out.println("采用适用于ＪＡＶＡ语言的ＵＴＦ－８字符编码");
		readBuff(buff);
		
	}
}
