14. String replaceAll

The easy way is to just use the String replace method that replaces a char sequence with another char sequence: str.replace("||", "| |"); If you want to "do it yourself," you'll probably want to use a StringBuffer since you'll be "mutating." You can use a loop to find the index of the first "||", then replace that substring (from index to ...

Remember that the second parameter of the replaceAll() method is not just a string. It is also a regex replacement string. The easiest way to figure out the correct number of backslashes is to deal with the regex first, and then the java string second. What you want is........ \" First, in regex (replacement string), the backslash has special meaning, so ...

19. String replaceAll problem with $

... which means you have to use the "escape character" to tell the regular expression compiler to ignore the "$". You have to use a backslash, but since in a Java String a backslash is special, too, you have to use two backslashes to get a literal backslash into the String: String y = "xy\\$z";

26. duplicating String's replaceAll() method in 1.3

Unfortunately, I don't think implementing an outside package will be an option. (Our data security dept. is extremely anal, and it would likely take an act of Congress to get this done.)

27. Strings replaceAll()

Sun has a tutorial on regular expressions, which I believe started either with Perl or C.

Correct: the second parameter is not an ordinary String, but it's not a regex String. The only thing special with it, is that variables are interpolated in it.

42. String.replaceAll strange behavior...

43. PatternSyntaxException with replaceAll(String, String);

The problem is that backslash is an escape both in Java string literals and also in regular expressions. To place a literal backslash in a regular expression you have to double it for the regexp escape, then double it again for the Java literal. So a single literal slash has to be typed as four. And I hope you aren't forgetting ...
