Problem when doing replace

[Ganesan Ramakrishnan]

Hi all,

Here is the string i typed into the text area

are

i want to print this 4 line into one line .
so output like this "hai all how are" in one line
i.e i want to replace the newline character with space

i have done like this store this string into one string
then
str.replaceAll("\\n","");

but its not working

 str.replaceAll("\\n","");   

Are you sure you are giving a "space" in your replace code , like this

 str.replaceAll("\\n"," ");   

[Ganesan Ramakrishnan]

yes is there .

But the problem is i am going to writing this string into .csv file is again showing the with newline.

Thanks
Ganesan

Are you sure you should use 2 \\ characters. I think you need only 1.
Try to replace \n and also assign the replaced value to your string.

str.replaceAll("\\n","");

with

str = str.replaceAll("\n","");

Ohh sory for that doubt !!

The problem is String#replaceAll() returns a new String object!!

So better you catch it , like

 String newString = str.replaceAll("\\n"," ");      

Try this ,

Hi

Thanks for all.

I tried before itself like String str = str.replaceAll("\n" , "");
but its not working.

But str = str.replaceAll("\r" , " ");

its working fine.

once again thanks for all
