Answer 1

Strings in java are immutable, so replaceAll returns a new string.

Do

 text = text.replaceAll(";", "");

Answer 2

You should not forget that String is immutable. So, whenever you want to modify it, you have to assign the result to a variable.

A possible solution to what you need:

if (text.endsWith(";") {
  text = text.substring(0, text.length() - 1);
}

Answer 3

public static void main(String[] args) {
    String text_original = "wherabouts;";
    char[] c = text_original.toCharArray();

    System.out.println("TEXT original: "+ text_original);

    String text_new = c[text_original.length()-1] == ';' ? text_original.substring(0,text_original.length()-2) : text_original;

    System.out.println("TEXT new: "+text_new);
}

Answer 4

text = text.replaceAll(";", "");

String is immutable so new String will be created after replace.

String newString = text.replace(";", "");

or

String newString = text.replaceAll(";$", "");
