This Example describes the way to append the String with the existing one using
expression. For this we are going to make program named Appendreplacement.java.
The steps involved in program Appendreplacement.java are described below:-
Pattern pattern = Pattern.compile("(Rose) (.net)"):-Creating a pattern object and compiling the given regular expression into a pattern. Here string "india" is the text to be placed between ((Rose) and (.net)).
String text = "Company in Rohini: Rose .net.": Declaring String where the text is to be appended.
m.appendReplacement(buffer, replacement): This is the append and replace step of the Matcher class.
Output of the program:-
Text before replacement is:Company in Rohini:- Rose .net.
Text before replacement is:Company in Rohini:- Roseindia .net
