There are a few ways to remove the last character from a string in Java. Here are three approaches you can use:

  1. Using the substring method:
String string = "Hello, World!";
String newString = string.substring(0, string.length() - 1);
  1. Using the StringBuilder class:
String string = "Hello, World!";
String newString = new StringBuilder(string).deleteCharAt(string.length() - 1).toString();
  1. Using the replaceFirst method with a regular expression:
String string = "Hello, World!";
String newString = string.replaceFirst(".$", "");

Note that the substring and StringBuilder approaches are generally preferred for performance and clarity. The replaceFirst method works but involves regex compilation overhead, making it slower for large strings or frequent operations. Also, ensure the string is not empty before applying these methods to avoid IndexOutOfBoundsException.
