一、java如何读取txt文件内容？
String a=;
BufferedReader reader=
new BufferedReader(new InputStreamReader(new FileInputStream(C:\\user.txt)));
String line=null;
for(;(line=reader.readLine())!=null;){
a+=line;
}
reader.close();
二、java 直接打开一个本地文件
rt.exec(cmd /c start \ + fd.getDirectory()+fd.getFile()+\);
三、java 打开本地文件
File file =new File(e:\iris.txt);
