The quoteReplacement(String string) method of Matcher Class is used to get the replacement String literal of the String passed as parameter. This String literal acts as the parameter for the replace methods. Hence quoteReplacement() method acts as the intermediate in the replace methods.
Syntax:
public static String quoteReplacement(String string)
Parameters: This method takes a parameter string which is the String to be replaced in the Matcher.
Return Value: This method returns a String literal which is the replacement String for the matcher.
Below examples illustrate the Matcher.quoteReplacement() method:
Example 1:
// Java code to illustrate quoteReplacement() method  import java.util.regex.*;  public class GFG {    public static void main(String[] args)    {          // Get the regex to be checked        String regex = "Geek";          // Create a pattern from regex        Pattern pattern = Pattern.compile(regex);          // Get the String to be matched        String            stringToBeMatched            = "GeeksForGeeks Geeks for For Geeks Geek";          // Create a matcher for the input String        Matcher matcher            = pattern                  .matcher(stringToBeMatched);          // Get the String to be replaced        String stringToBeReplaced = "Geeks";          // Get the String literal        // using quoteReplacement() method        System.out.println(            matcher                .quoteReplacement(stringToBeReplaced));    }} |
Output:
Geeks
Example 2:
// Java code to illustrate quoteReplacement() method  import java.util.regex.*;  public class GFG {    public static void main(String[] args)    {          // Get the regex to be checked        String regex = "FGF";          // Create a pattern from regex        Pattern pattern            = Pattern.compile(regex);          // Get the String to be matched        String            stringToBeMatched            = "GFGFGFGFGFGFGFGFGFG FGF GFG GFG FGF";          // Create a matcher for the input String        Matcher matcher            = pattern.matcher(stringToBeMatched);          // Get the String to be replaced        String stringToBeReplaced = "GFG";          // Get the String literal        // using quoteReplacement() method        System.out.println(            matcher                .quoteReplacement(stringToBeReplaced));          System.out.println(            matcher                .replaceAll(                    matcher                        .quoteReplacement(                            stringToBeReplaced)));    }} |
Output:
GFG GGFGGGFGGGFGGGFGGFG GFG GFG GFG GFG
