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

Reassign the variable to a substring:

s = s.substring(0, s.length() - 1)

Also an alternative way of solving your problem: you might also want to consider using a StringTokenizer to read the file and set the delimiters to be the characters you don't want to be part of words.
