replace all occurrences of a character in a string in java? [duplicate]

Question

A very noob question..

I want to replace all the occurance of "." in a string with empty space..

So this is what I tried

             String s = "1.2.3.4";
        System.out.println(s);
         s = s.replaceAll(".", " ");
        System.out.println(s);

But the second print is an empty print?

What did i missed here?

Answer 1

You want to escape the .. Otherwise, it can match anything.

Try s.replaceAll("\\.", " ") instead.

Answer 2

Use String.replace(char, char) instead of String.replaceAll
