Replace all the occurrence of {.?!"><',/\|@#$%^&*~`-_=+} with a word "myWord"

Question

For Example: input String is

Input =  "Hello there, How are you? Fine!! @xyz"

and the output would be

Output = "Hello there myWord How are you myWord Fine myWord myWord  myWord xyz"

i have tried with Pattern class and Matcher class but it only replaces one type of pattern and str.replace(".","myWord");

Answer 1

you can use [^\\w\\s]

\\s*[^\\w\\s]\\s* :\\s* mean one or more space

[^\\w\\s] : ^ don't capture \\w and \\s

\\w mean a-zA-Z0-9_

\\s mean space

    String s="Hello there, How are you? Fine!! @xyz";
    System.out.println(s.replaceAll("\\s*[^\\w\\s]\\s*", " myWord "));

Output :

Hello there myWord How are you myWord Fine myWord  myWord  myWord xyz

To avoid any other special character , that shouldn't be replaced then just add them inside this [] e.g \\s*[^\\w\\s:;\\[\\]]\\s* , as pointed by @brso05

Demo

const regex = /\s*[^\w\s\]\[;]\s*/g;
const str = `Hello there, How are you? Fine!! ; @xyz []`;
const subst = ` myWord `;
const result = str.replace(regex, subst);
console.log(result);
