How do I remove some characters from my String

Question

i want to remove all of the following chars from my string

">[],-"

at the moment im doing this. but there must be a more efficient way

newString = myString.replace(">","").replace("[","").replace("]","")....

Answer 1

Use a regex that describes all the characters you want to replace, with the method that replaces everything matching the regex:

newString = myString.replaceAll("[<>\\[\\],-]", "");

(edited: I don't think <> are supposed to be escaped, actually. And I forgot to double up the backslashes since they'll be interpreted twice: once by the Java compiler, and again by the regular expression engine.)

Answer 2

newString = myString.replaceAll("[>\\[\\],-]", "");

The backslashes are to escape the '[' because the first argument is actually a regular expression.
