replace multiple words in a string in java

  String originalString = "Here is a string with words that need to be replaced"; 
  String replacedString = originalString.replaceAll("words","characters"); 
  System.out.println(replacedString); 

This code declares a variable originalString and assigns it a string value. It then uses the replaceAll method of the String class to replace the word “words” with “characters” in the originalString variable and assigns the new string to the variable replacedString. Finally, it prints out the value of the replacedString variable using the println method of the System class.
