Getting the Last token from a String

[Prem Bhazee]

Hi Ranchers,

I have a string from which I need to get the last token and the token changes everytime based on the string value.I am planning to use String tokenizer with hasMoreTokens method. Haven't come with the code as of it. Is there any other ways of getting the last token of a string variable. Please let me know.

Thanks in advance

Use String.split() and then just get the last element of the returned array.

Hi

I am using String split to split my string.This is the method I have written.

strValue = "abc!$#cde!$#def"

 private String getltToken(String strValue,"!$#" )
{
String[] strArray;
String strlttoken = null;

strArray = strValue.split("!$#");

for(int i =0; i < strArray.length ; i++) {
strlttoken = strArray[strArray.length-1];   
}
return strlttoken;

}   

But it returns the whole string and also I tried with "\\!$#" still same result.

Can you please help

Hi,
I tried "!\\$#" and it worked. My understanding is that $ is regular-expression constructs so that it had to be trailed with \\.

Just curious is this the correct reason.

Thanks

I think you are correct, yes.

Lots more about regular expressions here. The $ is one of several "meta-characters."

Try the simpler approach

String s = "Hello world again";
int i = s.lastIndexOf(' ');
String buffer = s.substring(i+1);
System.out.println(buffer);

The output will be: again

Welcome to the Ranch
Yes, that approach would work.
