java regular expression problem

[ranumehta79]

Hi,

I want to replace mulitple occurances of a string one after the another
with a single string

for eg .

input : a hello b world c java abcabcabc
output: a hello b world c java def

I mean multiple occurances of pattern 'abc' with a single string 'def'.


how can do this with JAVA regular expressions ?

I tried replaceAll method in string class, but I dont know how to
format regular expression.

thanks
Ranu

public class Ranu{
public static void main(String[] args){
String text = "a hello b world c java abcabcabc";

System.out.println(text.replaceAll("(?:abc)+", "def"));
}
}

}
}

or,
System.out.println(text.replaceAll("(?:abc){2,}", "def"));

For clarity to the OP: This version replaces multiple occurrences, but
not a stand-alone occurrence. E.g., XabcabcX becomes XdefX, but XabcX
remains XabcX.
