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();
    
    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...");
    
  }


  
}
