Vector<FileInputStream>(); //2.定义被打包的文件，这些文件必须存在，new File 不负责建新文件 File fileA = new
File("a.txt"); File fileB = new
File("b.txt"); File fileC = new
File("c.txt"); //3.将文件打包 vector.add(new
FileInputStream(fileA)); vector.add(new
FileInputStream(fileB)); vector.add(new
FileInputStream(fileC)); //4.用序列流进行合并 SequenceInputStream sts = new
SequenceInputStream(vector.elements()); //5.将序列流输出到一个文本上 File fileD = new
File("d.txt"); FileOutputStream out = new
FileOutputStream(fileD); //自定义缓冲区 byte[] bytes = new
byte[1024]; int
count = 0; while((count = sts.read(bytes)) != -1){ out.write(bytes, 0, count); } //一定要记得关闭流 sts.close(); out.close(); }} |
