Java - How to remove all special character in a string except dot and comma

To remove all special characters from a string except dot (.) and comma ( ), you can use a regular expression along with the replaceAll method in Java. Here's an example:

public class RemoveSpecialCharacters { public static void main(String[] args) { String inputString = "Hello! This is a string with special characters, @ and $."; // Remove all special characters except dot and comma String result = removeSpecialCharacters(inputString); System.out.println("Original String: " + inputString); System.out.println("Result String: " + result); } public static String removeSpecialCharacters(String input) { // Use regular expression to remove special characters // [^a-zA-Z0-9.,] matches any character that is not a letter, digit, dot, or comma return input.replaceAll("[^a-zA-Z0-9.,]", ""); } }

In this example:

  • The removeSpecialCharacters method uses the replaceAll method with a regular expression ([^a-zA-Z0-9.,]) to remove all characters that are not letters, digits, dots, or commas.

  • The regular expression breakdown:

    • [^...]: Matches any character that is not in the specified set.
    • a-zA-Z: Matches any letter (uppercase or lowercase).
    • 0-9: Matches any digit.
    • .,: Matches dot (.) and comma ( ).

  • The result is the original string with all other special characters removed.

Adjust the input string as needed for your specific use case.
