Newline character omitted while reading from buffer

Question

I\'ve written the following code:

public class WriteToCharBuffer {

 public static void main(String[] args) {
  String text = \"This is the data to write in          


        

Answer 1

Just in case someone wants to read the text with '\n' included.

try this simple approach

So,

Say, You have three lines of data (say in a .txt file) , like this

This is the data to write in buffer!
This is the second line
This is the third line

And while reading, you are doing something like this

    String content=null;
    String str=null;
    while((str=bufferedReader.readLine())!=null){ //assuming you have 
    content.append(str);                     //your bufferedReader declared.
    }
    bufferedReader.close();
    System.out.println(content);

and expecting the output to be

This is the data to write in buffer!
This is the second line
This is the third line

but scratching your head upon seeing output as a single line

This is the data to write in buffer!This is the second lineThis is the third line

Here is what you can do

by adding this piece of code inside your while loop

if(str.trim().length()==0){
   content.append("\n");
}

So now what your while loop should look like

while((str=bufferedReader.readLine())!=null){
    if(str.trim().length()==0){
       content.append("\n");
    }
    content.append(str);
}

Now you get required output (as three lines of text)

This is the data to write in buffer!
This is the second line
This is the third line
