Remove brackets () from Phone Number string – Java | JavaScript

Hi Guy’s Welcome to Proto Coders Point. In this Article let’s check out How to remove brackets () from Phone Number String, With Java & JavaScript Code Example.

Java & JavaScript Code to check if phone number string contains () brackets and remove the brackets

Example:

+91 (123) 867 456              --->          +91 123 867 456

Java Code

public static void main(String[] args) {
      String phoneNo = "+91 (123) 867 456";
      Boolean bool = false;

      if(phoneNo.contains("(") || phoneNo.contains(")")){
          bool = true;
       }


      if(bool){
        String newphoneno = phoneNo.substring(0,4) + phoneNo.substring(5,8) + phoneNo.substring(9,phoneNo.length());
        
        System.out.println(""+newphoneno);
        //use replaceAll if you want to remove all empty spaces from string.
        System.out.println(""+newphoneno.replaceAll("\\s", ""));
        
   }
 }

use replaceAll(“\s”, “”) if you want to remove all empty spaces from string.

JavaScript Code

let phoneNo = "+91 (123) 867 456";
let bool = false;

if(phoneNo.includes("(") || phoneNo.includes(")")){
    bool = true;
}


if(bool){
    var newphoneno = phoneNo.substring(0,4) + phoneNo.substring(5,8)+phoneNo.substring(9,phoneNo.length);
}
console.log(newphoneno)
//use replace with regex if you want to remove all empty spaces from string.
console.log(newphoneno.replace(/\s+/g,''))

Here to remove spaces between the phone number string I am using replace with regular expression.
