How To Replace Char In String In Java
In Java, you can replace characters in a string by utilizing the replace() method. This method takes two parameters — the character you want to replace and the character you want to replace it with. It then returns a new string with the specified replacements. For example, if you have a string “hello” and you want to replace ‘e’ with ‘a’, you can use the code snippet “String newString = originalString.replace(‘e’, ‘a’);” This will result in the newString variable holding the value “hallo”.
