How do I delete specific characters from a particular String in Java?

Question

For example I\'m extracting a text String from a text file and I need those words to form an array. However, when I do all that some words end with comma (,) or a full stop (.)

Answer 1

Use:

String str = "whatever";
str = str.replaceAll("[,.]", "");

replaceAll takes a regular expression. This:

[,.]

...looks for each comma and/or period.
