Replace white space with %20

Question

I have to replace all withe space in a string with %20.

I try to use the method replaceAll in this mode title.replaceAll(" ", "%20");(obviously title is a String) but this doesn't work and the results is the initial string with all white space

You did capture the new String into another variable, right? (hard to tell since you didn't provide enough code to say ...) — AntonH, Aug 08 '17 at 17:40
Strings are immutable in Java. Try `String replaced = title.replaceAll(" ", "%20");` — janos, Aug 08 '17 at 17:40

Solution

Don't use replace all I find it doesn't ever work as expected. Just String.replace and that should get the job done just fine.

public static void main (String [] args) {

    String test = "H E L L O";

    test = test.replace(" ", "%20");
    System.out.println (test);

}

Result

H%20E%20L%20L%20O
