How to use replace(char, char) to replace all instances of character b with nothing

Question

How do i use replace(char, char) to replace all instances of character "b" with nothing.

For example:

Hambbburger to Hamurger

EDIT: Constraint is only JDK 1.4.2, meaning no overloaded version of replace!

Answer 1

There's also a replaceAll function that uses strings, note however that it evals them as regexes, but for replacing a single char will do just fine.

Here's an example:

String meal = "Hambbburger";

String replaced = meal.replaceAll("b","");

Note that the replaced variable is necessary since replaceAll doesn't change the string in place but creates a new one with the replacement (String is immutable in java).

If the character you want to replace has a different meaning in a regex (e.g. the . char will match any char, not a dot) you'll need to quote the first parameter like this:

String meal = "Ham.bur.ger";

String replaced = meal.replaceAll(Pattern.quote("."),"");

Answer 2

Strings are immutable, so make sure you assign the result to a string.

String str = "Hambbburger";
str = str.replace("b", "");

You don't need replaceAll if you use Java 6. See here: replace

Answer 3

String text = "Hambbburger";
text = text.replace('b', '\0');

The '\0' represents NUL in ASCII code.
