Java string: replace the string containing the $ sign

Question

How to replace String $1with Java? I tried this, but this does not replace it:

System.out.println(someHTMLCodeAsString.replaceAll("$1", "REPLACED"));

Answer 1

The value of $ is interpreted as a regular expression, and not as a character (this means "end of line"). TrySystem.out.println(someHTMLCodeAsString.replaceAll("\\$1", "REPLACED"));

Answer 2

to try

 System.out.println(someHTMLCodeAsString.replace("$1", "REPLACED"));

Answer 3

Answer 4

You have a bit and bits of answer. Peter Laurie is right. You need to avoid $ with a regular expression excerpt rather than an escape string, so double \.

System.out.println (someHTMLCodeAsString.replaceAll ("\\ $ 1", "REPLACED"));

Answer 5

Or, let the regex library process it for you:

someHTMLCodeAsString.replaceAll(Pattern.quote("$1"), "REPLACED")

Answer 6

You can simply use this method:

someHTMLCodeAsString.replaceAll("\\$1", "REPLACED").

Just replace all "$" with "REPLACED"!
