使用java合并两个已存在的文件的内容到一个新的文件去

import java.io.*;
package com.zuidaima.file.util;
/**

class combinefile{
	public static void main(String[] args) throws IOException {

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		//get the path of file
		System.out.print("please enter the path of first file");
		String filebr1=br.readLine();
		System.out.print("please enter the path of second file");
		String filebr2=br.readLine();
		System.out.print("please input the path of combine file");
		String filebr3=br.readLine();
		//transform the real file into object;
		File file1 = new File(filebr1);
		File file2 = new File(filebr2);
		File file3 = new File(filebr3);
		//transform file1 and file2 object into inputstream
		FileInputStream fis1 = new FileInputStream(file1);
		FileInputStream fis2 = new FileInputStream(file2);
		//transform file3 object into outputstream
		FileOutputStream fos = new FileOutputStream(file3);
		//combine two stream into one stream
		InputStream is = new SequenceInputStream(fis1,fis2);

		int c;
		while((c=is.read())!=-1)
		{
			fos.write((char)c);
		}

		System.out.println("OK");
		is.close();
		fos.close();
	}
}
