本文實例為大家分享了Java實現多個文檔合并輸出到一個文檔的具體代碼，供大家參考，具體內容如下

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();

									    for(int i =0; i<iF.length; 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...");

									  }
