java 文件流下载word java文件流保存成文件

无论是二进制数据还是字符数据（文本数据），都可以用文件输出流java.io.FileOutputStream，以字节流的方式保存到指定文件。

package test;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;class LogWrite{
 private static boolean fileLog = true;
 private static String logFileName = "E:/workspace/Java/result/result.txt";//指定程序执行结果保存的文件路径
 public static OutputStream getOutputStream() throws IOException{
 if(fileLog)
 {
 File file = new File(logFileName);
 if(!file.exists())
 file.createNewFile();
 return new FileOutputStream(file, true); 
 }
 else
 {
 return System.out;
 } 
 }
 public static void log(String info) throws IOException{
 OutputStream out = getOutputStream();
 out.write(info.getBytes("utf-8"));
 }

}
public class Test1 { public static void main(String[] args) throws IOException {
 // TODO Auto-generated method stub
 LogWrite.log("hello world");//"hello world"会保存到result.txt文件中
 }}
