rtrim function in jdk 1.4

[sudha swami]

Hi,

Currently i am using jdk 1.4.
I want to remove new line character and carriage return from the end of the String. Do we have the functionality of rtrim in java?
I dont want to remove any leading spaces.

thanks
sudha

There isn't just rtrim, but it's not too hard to do yourself:

// assumption: the string is not empty
int index = string.length();
while (index > 0 && Character.isWhitespace(string.charAt(index - 1)))
{
    index--;
}
// index == 0 or string.charAt(index - 1) is not white space
// index == 0 means the entire string is white space; substring will return the empty string
string = string.substring(0, index);

Regex will also work here...

string = string.replaceFirst("[\\n\\r]*$", "");

And this is the equivalent of Rob's solution...

string = string.replaceFirst("[\\s]*$", "");
