合并流

合并流的主要功能是将两个文件的内容合并成一个文件。

如果要实现合并流，则必须使用SequenceInputStream类

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.SequenceInputStream;

//=================================================
// File Name       :	SequenceInputStream_demo
//------------------------------------------------------------------------------
// Author          :	Common



//主类
//Function        : 	SequenceInputStream_demo;
public class SequenceInputStream_demo {

	public static void main(String[] args) throws Exception{
		// TODO 自动生成的方法存根
		InputStream is1 = null;				//输入流1
		InputStream is2 = null;				//输入流2
		OutputStream os = null;				//输出流
		SequenceInputStream sis = null;	//合并流
		
		is1 = new FileInputStream("/home/common/software/coding/HelloWord/HelloWord/a.txt");
		is2 = new FileInputStream("/home/common/software/coding/HelloWord/HelloWord/b.txt");
		os = new FileOutputStream("/home/common/software/coding/HelloWord/HelloWord/ab.txt");
		sis = new SequenceInputStream(is1,is2);				//实例化合并流
		int temp = 0;
		while((temp = sis.read()) != -1){
			os.write(temp);
		}
		sis.close();
		is1.close();
		is2.close();
		os.close();
	}

}
