Java实现多个文档合并输出到一个文档

Java实现多个文档合并输出到一个文档

本文实例为大家分享了java实现多个文档合并输出到一个文档的具体代码，供大家参考，具体内容如下

方法：Java NIO

package First;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.nio.channels.FileChannel;

import java.nio.channels.WritableByteChannel;

public class Test {

public static void main(String params[]) throws Exception {

String[] iF = new String[] {"E:/test1.txt", "E:/test2.txt", "E:/test3.txt", "E:/test4.txt" };

String oF = "E:/out.txt";

FileOutputStream output = new FileOutputStream(new File(oF));

WritableByteChannel targetChannel = output.getChannel();

http://

for(int i GKPsl=0; i

FileInputStream input = new FileInputStream(iF[i]);

FileChannel inputChannel = input.getChannel();

inputChannel.transferTo(0, inputChannel.size(), targetChannel);

inputChannel.close();

input.close();

}

targetChannel.close();

output.close();

System.out.println("All jobs done...");

}

}

GKPsl

FileInputStream input = new FileInputStream(iF[i]);

FileChannel inputChannel = input.getChannel();

inputChannel.transferTo(0, inputChannel.size(), targetChannel);

inputChannel.close();

input.close();

}

targetChannel.close();

output.close();

System.out.println("All jobs done...");

}

}
