How to count replace first occourance of a String?
Following example demonstrates how to replace first occourance of a String in a String using replaceFirst() method of a Matcher class.
import java.util.regex.Matcher; import java.util.regex.Pattern; public class Main { public static void main(String args[]) { Pattern p = Pattern.compile("hello"); String instring = "hello hello hello."; System.out.println("initial String: "+ instring); Matcher m = p.matcher(instring); String tmp = m.replaceFirst("Java"); System.out.println("String after replacing 1st Match: " +tmp); } }
The above code sample will produce the following result.
initial String: hello hello hello. String after replacing 1st Match: Java hello hello.
