Java 操作数组的流

package io.p6.bytestream;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;

public class byteArrayStreamDemo {

	public static void main(String[] args) throws IOException {
		ByteArrayInputStream bis=new ByteArrayInputStream("abcdefg".getBytes());//如果源或者目的是内存  操作内存的
		
		ByteArrayOutputStream bos=new ByteArrayOutputStream();
		int ch=0;
		while((ch=bis.read())!=-1) {
			bos.write(ch);
		}
		System.out.println(bos.toString());
	}
