txt资料读写

txt文件读写
    针对txt,csv文件的读写可以使用java的读写操作。
以下是一个简单的例子：

private static void readtxt(string path){		try {			inputstream in = new fileinputstream(path);			bufferedreader br = new bufferedreader(new inputstreamreader(in,"gb2312"));			string tmp = "";			while((tmp=br.readline())!=null){				system.out.println(tmp);			}			br.close();			in.close();		} catch (filenotfoundexception e) {			e.printstacktrace();		} catch (ioexception e) {			e.printstacktrace();		}	}		private static void writetxt(string path){		try{			outputstream ou = new fileoutputstream(path);			bufferedwriter bw = new bufferedwriter(new outputstreamwriter(ou,"gb2312"));			bufferedreader br = new bufferedreader(new inputstreamreader(system.in,"utf-8"));			string tmp = "";			while((tmp=br.readline())!=null&&!tmp.equals("exit")){				bw.write(tmp);				bw.flush();				bw.newline();			}			br.close();			bw.close();			ou.close();		}catch(exception e){			e.printstacktrace();		}	}
