//out = new PrintWriter(new FileOutputStream(f));

in2 =new BufferedReader(new FileReader(fe));

str=in2.readLine();

if(str!=null)

nn2=str;

str=in2.readLine();

try{

while((str)!=null)

{ nn2=nn2+"\n"+str;

str=in2.readLine();

}}catch(NullPointerException e){}

jta2.setText(nn2);

in2.close();

// in2 = new BufferedReader(new FileReader(fe));

}catch (IOException ex){
