I don't understand the question.

Perhaps if you provided some examples, and explained exactly what you want to happen and why.

The first parameter of the replaceAll method is a regular expression, so you need to find a regular expression that matches 'or' with no other letters either side of it. There are plenty of regular expression tutorials on the web if you don't know much about them.

it would be really helpful if you can tell me how to represent or in regex? i urgently need it please

Wow... I had to read this five times, before I finally got it....

I think it says ...

how do I replace the word "or" with a "newline" ? If i do it by calling the replaceAll() method, it replaces the "or" between the words too. For example, like in the word "borrow", the "or" sub-word is replaced. that is, the "b" is in one line and the "row" is in the other. I want to know a function that doesn't do this

Anyway...

Regular expressions has the "\b" tag, that is used to specify word boundaries.

Henry has explained the question nicely. You have helped me in previous posts too to understand the OP..

There is a way to do it without \b. But \b will be good as it is easy to understand..

Welcome to the Ranch

Just think how much sooner you would have had answers if anybody could understand your question. And we don’t use words like urgently.

this is my code . Its not giving the desired output.only "." is being replaced .
Please help

Does it mean you wish to replace and/AND from every line with a new line character?

This "not working" is different from the previous "not working". In the previous, too many "or"s were being replaced. It this one, it is not getting replaced at all. So, it is safe to assume that this lack of replacement is caused by recent changes.

You have written unnecessary if clauses in your code. As replaceAll() method need a regex, we can send case insensitive with regex..!

eg:-

data=strLine.replaceAll("(?i)but","\n\r");

No need of if clause at all..

Not this, But I saw a big problem in your if clause..! I think you have to add "\n" to variable data in if block too. If not, you are not moving into a new line. And I think that's why your code is working to "." only..!

[Campbell Ritchie]

Why are you using the escape sequences in the first place? They are platform‑specific and cannot be relied upon to work correctly. Please check this code carefully before use, in case I have spelt something wrongly.

package resources;
public class Constants
{
   private Constants()
   {
      // never called: uninstantiable class
   }

   public static final String LINE_END = System.getProperty("line.separator");
   // ... etc
}

You can use the LINE_END value wherever it is needed, possibly via static import.

You know what vaishnavi?

Write down the rules: All of them, and in sequence; because if you don't, you'll be forever wondering if you missed one. And you won't be helping us to help you.
